| 24 | <p>Libxml2 is the XML C parser and toolkit developed for the Gnome project
|
|---|
| 25 | (but usable outside of the Gnome platform), it is free software available
|
|---|
| 26 | under the <a href="http://www.opensource.org/licenses/mit-license.html">MIT
|
|---|
| 27 | License</a>. XML itself is a metalanguage to design markup languages, i.e.
|
|---|
| 28 | text language where semantic and structure are added to the content using
|
|---|
| 29 | extra "markup" information enclosed between angle brackets. HTML is the most
|
|---|
| 30 | well-known markup language. Though the library is written in C <a
|
|---|
| 31 | href="python.html">a variety of language bindings</a> make it available in
|
|---|
| 32 | other environments.</p>
|
|---|
| 33 |
|
|---|
| 34 | <p>Libxml2 is known to be very portable, the library should build and work
|
|---|
| 35 | without serious troubles on a variety of systems (Linux, Unix, Windows,

|
|---|
| 123 |
|
|---|
| 124 | <p>This document describes libxml, the <a
|
|---|
| 125 | href="http://www.w3.org/XML/">XML</a> C parser and toolkit developed for the
|
|---|
| 126 | <a href="http://www.gnome.org/">Gnome</a> project. <a
|
|---|
| 127 | href="http://www.w3.org/XML/">XML is a standard</a> for building tag-based
|
|---|

|
|---|
| 130 | <p>Here are some key points about libxml:</p>
|
|---|
| 131 | <ul>
|
|---|
| 132 | <li>Libxml2 exports Push (progressive) and Pull (blocking) type parser
|
|---|
| 133 | interfaces for both XML and HTML.</li>
|
|---|
| 134 | <li>Libxml2 can do DTD validation at parse time, using a parsed document
|
|---|
| 135 | instance, or with an arbitrary DTD.</li>
|
|---|
| 136 | <li>Libxml2 includes complete <a
|
|---|
| 137 | href="http://www.w3.org/TR/xpath">XPath</a>, <a
|
|---|
| 138 | href="http://www.w3.org/TR/xptr">XPointer</a> and <a
|
|---|
| 139 | href="http://www.w3.org/TR/xinclude">XInclude</a> implementations.</li>
|
|---|
| 140 | <li>It is written in plain C, making as few assumptions as possible, and
|
|---|
| 141 | sticking closely to ANSI C/POSIX for easy embedding. Works on
|
|---|
| 142 | Linux/Unix/Windows, ported to a number of other platforms.</li>
|
|---|
| 143 | <li>Basic support for HTTP and FTP client allowing applications to fetch
|
|---|
| 144 | remote resources.</li>
|
|---|
| 145 | <li>The design is modular, most of the extensions can be compiled out.</li>
|
|---|
| 146 | <li>The internal document representation is as close as possible to the <a
|
|---|
| 147 | href="http://www.w3.org/DOM/">DOM</a> interfaces.</li>
|
|---|
| 148 | <li>Libxml2 also has a <a

|
|---|
| 150 | the interface is designed to be compatible with <a

|

| 208 | <li>If you are not doing development, you can safely install both.
|
|---|
| 209 | Usually the packages <a
|
|---|
| 210 | href="http://rpmfind.net/linux/RPM/libxml.html">libxml</a> and <a
|
|---|
| 211 | href="http://rpmfind.net/linux/RPM/libxml2.html">libxml2</a> are
|
|---|
| 212 | compatible (this is not the case for development packages).</li>
|
|---|
| 213 | <li>If you are a developer and your system provides separate packaging
|
|---|
| 214 | for shared libraries and the development components, it is possible
|
|---|
| 215 | to install libxml and libxml2, and also <a

|

| 224 | <li><em>I can't install the libxml package, it conflicts with libxml0</em>
|

| 225 | <p>You probably have an old libxml0 package used to provide the shared
|
|---|
| 226 | library for libxml.so.0, you can probably safely remove it. The libxml
|
|---|
| 227 | packages provided on <a
|
|---|
| 228 | href="ftp://xmlsoft.org/libxml2/">xmlsoft.org</a> provide
|

| 231 | <li><em>I can't install the libxml(2) RPM package due to failed

|---|
| 232 | dependencies</em>
|
|---|
| 233 | <p>The most generic solution is to re-fetch the latest src.rpm , and
|
|---|
| 234 | rebuild it locally with</p>
|
|---|
| 235 | <p><code>rpm --rebuild libxml(2)-xxx.src.rpm</code>.</p>
|
|---|
| 236 | <p>If everything goes well it will generate two binary rpm packages (one

|---|
| 237 | providing the shared libs and xmllint, and the other one, the -devel
|

|
|---|
| 244 | <ol>
|
|---|
| 245 | <li><em>What is the process to compile libxml2 ?</em>
|
|---|
| 246 | <p>As most UNIX libraries libxml2 follows the "standard":</p>
|
|---|
| 247 | <p><code>gunzip -c xxx.tar.gz | tar xvf -</code></p>
|
|---|
| 248 | <p><code>cd libxml-xxxx</code></p>
|
|---|
| 249 | <p><code>./configure --help</code></p>
|
|---|
| 250 | <p>to see the options, then the compilation/installation proper</p>
|
|---|
| 251 | <p><code>./configure [possible options]</code></p>
|
|---|
| 252 | <p><code>make</code></p>
|
|---|
| 253 | <p><code>make install</code></p>
|
|---|
| 254 | <p>At that point you may have to rerun ldconfig or a similar utility to
|
|---|
| 255 | update your list of installed shared libs.</p>
|
|---|
| 256 | </li>
|
|---|
| 257 | <li><em>What other libraries are needed to compile/install libxml2 ?</em>
|
|---|
| 258 | <p>Libxml2 does not require any other library, the normal C ANSI API
|
|---|
| 259 | should be sufficient (please report any violation to this rule you may
|
|---|
| 260 | find).</p>
|
|---|
| 261 | <p>However if found at configuration time libxml2 will detect and use the
|
|---|
| 262 | following libs:</p>
|
|---|
| 263 | <ul>
|
|---|
| 264 | <li><a href="http://www.info-zip.org/pub/infozip/zlib/">libz</a> : a
|
|---|
| 265 | highly portable and available widely compression library.</li>
|
|---|
| 266 | <li>iconv: a powerful character encoding conversion library. It is
|
|---|
| 267 | included by default in recent glibc libraries, so it doesn't need to
|
|---|
| 268 | be installed specifically on Linux. It now seems a <a
|
|---|
| 269 | href="http://www.opennc.org/onlinepubs/7908799/xsh/iconv.html">part
|
|---|
| 270 | of the official UNIX</a> specification. Here is one <a
|
|---|
| 271 | href="http://www.gnu.org/software/libiconv/">implementation of the
|
|---|
| 272 | library</a> which source can be found <a

|
|---|
| 274 | </ul>
|
|---|
| 275 | </li>
|
|---|
| 276 | <p></p>
|
|---|
| 277 | <li><em>Make check fails on some platforms</em>
|
|---|
| 278 | <p>Sometimes the regression tests' results don't completely match the
|
|---|
| 279 | value produced by the parser, and the makefile uses diff to print the

|

| 300 | <li><em>Troubles compiling or linking programs using libxml2</em>
|
|---|
| 301 | <p>Usually the problem comes from the fact that the compiler doesn't get
|
|---|
| 302 | the right compilation or linking flags. There is a small shell script
|
|---|
| 303 | <code>xml2-config</code> which is installed as part of libxml2 usual
|
|---|
| 304 | install process which provides those flags. Use</p>
|
|---|
| 305 | <p><code>xml2-config --cflags</code></p>
|
|---|
| 306 | <p>to get the compilation flags and</p>
|
|---|
| 307 | <p><code>xml2-config --libs</code></p>
|
|---|
| 308 | <p>to get the linker flags. Usually this is done directly from the
|
|---|
| 309 | Makefile as:</p>
|
|---|
| 310 | <p><code>CFLAGS=`xml2-config --cflags`</code></p>
|
|---|
| 311 | <p><code>LIBS=`xml2-config --libs`</code></p>
|
|---|
| 312 | </li>
|
|---|
| 313 | <li><em>I want to install my own copy of libxml2 in my home directory and
|
|---|
| 314 | link my programs against it, but it doesn't work</em>
|
|---|
| 315 | <p>There are many different ways to accomplish this. Here is one way to
|
|---|
| 316 | do this under Linux. Suppose your home directory is <code>/home/user.
|
|---|
| 317 | </code>Then:</p>
|
|---|
| 318 | <ul>
|
|---|
| 319 | <li>Create a subdirectory, let's call it <code>myxml</code></li>
|
|---|
| 320 | <li>unpack the libxml2 distribution into that subdirectory</li>
|
|---|
| 321 | <li>chdir into the unpacked distribution
|
|---|
| 322 | (<code>/home/user/myxml/libxml2 </code>)</li>
|
|---|
| 323 | <li>configure the library using the "<code>--prefix</code>" switch,
|
|---|
| 324 | specifying an installation subdirectory in
|
|---|
| 325 | <code>/home/user/myxml</code>, e.g.
|
|---|
| 326 | <p><code>./configure --prefix /home/user/myxml/xmlinst</code> {other
|
|---|
| 327 | configuration options}</p>
|
|---|
| 328 | </li>
|
|---|
| 329 | <li>now run <code>make</code> followed by <code>make install</code></li>
|
|---|
| 330 | <li>At this point, the installation subdirectory contains the complete
|
|---|
| 331 | "private" include files, library files and binary program files (e.g.
|
|---|
| 332 | xmllint), located in
|
|---|
| 333 | <p><code>/home/user/myxml/xmlinst/lib,
|
|---|
| 334 | /home/user/myxml/xmlinst/include </code> and <code>
|
|---|
| 335 | /home/user/myxml/xmlinst/bin</code></p>
|
|---|
| 336 | respectively.</li>
|
|---|
| 337 | <li>In order to use this "private" library, you should first add it to
|
|---|
| 338 | the beginning of your default PATH (so that your own private program
|
|---|
| 339 | files such as xmllint will be used instead of the normal system
|
|---|
| 340 | ones). To do this, the Bash command would be
|
|---|
| 341 | <p><code>export PATH=/home/user/myxml/xmlinst/bin:$PATH</code></p>
|
|---|
| 342 | </li>
|
|---|
| 343 | <li>Now suppose you have a program <code>test1.c</code> that you would
|
|---|
| 344 | like to compile with your "private" library. Simply compile it using
|
|---|
| 345 | the command
|
|---|
| 346 | <p><code>gcc `xml2-config --cflags --libs` -o test test.c</code></p>
|
|---|
| 347 | Note that, because your PATH has been set with <code>
|
|---|
| 348 | /home/user/myxml/xmlinst/bin</code> at the beginning, the xml2-config
|
|---|
| 349 | program which you just installed will be used instead of the system
|
|---|
| 350 | default one, and this will <em>automatically</em> get the correct
|
|---|
| 351 | libraries linked with your program.</li>
|
|---|
| 352 | </ul>
|
|---|
| 353 | </li>

| 355 | <p></p>
|
|---|
| 356 | <li><em>xmlDocDump() generates output on one line.</em>
|
|---|
| 357 | <p>Libxml2 will not <strong>invent</strong> spaces in the content of a
|
|---|
| 358 | document since <strong>all spaces in the content of a document are
|
|---|
| 359 | significant</strong>. If you build a tree from the API and want
|
|---|
| 360 | indentation:</p>
|
|---|
| 361 | <ol>
|
|---|
| 362 | <li>the correct way is to generate those yourself too.</li>
|
|---|
| 363 | <li>the dangerous way is to ask libxml2 to add those blanks to your
|
|---|
| 364 | content <strong>modifying the content of your document in the
|
|---|
| 365 | process</strong>. The result may not be what you expect. There is

| 581 | href="mailto:[email protected]">[email protected]</a> list; if it's really libxml
|
|---|
| 582 | related I will approve it. Please do not send mail to me directly, it makes
|

| 583 | things really hard to track and in some cases I am not the best person to

|

| 585 |
|

| 586 | <p>To <span style="color: #E50000">be really clear about support</span>:</p>

| 588 | <li>Support or help <span style="color: #E50000">requests MUST be sent to

|
|---|
| 591 | message "I want free support but I don't want to share the benefits with
|

| 596 | your question remains unanswered after a week, repost it, making sure you

|
|---|
| 598 | <li>Failing to provide information as requested or double checking first
|
|---|
| 599 | for prior feedback also carries the implicit message "the time of the

| 604 | <p>Of course, bugs reported with a suggested patch for fixing them will
|

| 605 | probably be processed faster than those without.</p>

|
|---|
| 609 | provide the answer. I usually send source samples when answering libxml2

| 612 | not as polished as I would like (i need to learn more about DocBook), but

| 3459 | <ul>
|

| 3460 | <li>First public release of libxml2. If you are using libxml, it's a good
|
|---|
| 3461 | idea to check the 1.x to 2.x upgrade instructions. NOTE: while initially
|
|---|
| 3462 | scheduled for Apr 3 the release occurred only on Apr 12 due to massive
|
|---|
| 3463 | workload.</li>
|
|---|
| 3464 | <li>The include are now located under $prefix/include/libxml (instead of

|
|---|
| 3476 | <li>The I/O interface has been revamped. There is now ways to plug in
|
|---|
| 3477 | specific I/O modules, either at the URI scheme detection level using
|
|---|
| 3478 | xmlRegisterInputCallbacks() or by passing I/O functions when creating a
|
|---|
| 3479 | parser context using xmlCreateIOParserCtxt()</li>
|
|---|
| 3480 | <li>there is a C preprocessor macro LIBXML_VERSION providing the version
|
|---|
| 3481 | number of the libxml module in use</li>
|

|
|---|
| 3494 | <li>This includes a very large set of changes. From a programmatic point
|
|---|
| 3495 | of view applications should not have to be modified too much, check the

|
|---|
| 3520 | <li>It is possible to disable the ignorable blanks heuristic used by
|
|---|
| 3521 | libxml-1.x, a new function xmlKeepBlanksDefault(0) will allow this. Note
|
|---|
| 3522 | that for adherence to XML spec, this behaviour will be disabled by
|
|---|

|

| 3524 | old code.</li>

|
|---|
| 3601 | <li>Integrated various patches, especially a speedup improvement for large

|---|
| 3627 | 1.7.1 from <strong>CHAR</strong> to <strong>xmlChar</strong>. The reason

| 3629 | on non WIN32 environment, compatibility is provided by the way of a
|
|---|
| 3630 | <strong>#define </strong>.</li>

|
|---|
| 3667 | <p>The first line specifies that it is an XML document and gives useful
|
|---|
| 3668 | information about its encoding. Then the rest of the document is a text
|
|---|
| 3669 | format whose structure is specified by tags between brackets. <strong>Each
|
|---|
| 3670 | tag opened has to be closed</strong>. XML is pedantic about this. However, if
|
|---|
| 3671 | a tag is empty (no content), a single tag can serve as both the opening and
|
|---|
| 3672 | closing tag if it ends with <code>/></code> rather than with
|
|---|
| 3673 | <code>></code>. Note that, for example, the image tag has no content (just
|
|---|
| 3674 | an attribute) and is closed by ending the tag with <code>/></code>.</p>
|
|---|
| 3675 |
|
|---|
| 3676 | <p>XML can be applied successfully to a wide range of tasks, ranging from
|
|---|
| 3677 | long term structured document maintenance (where it follows the steps of
|
|---|
| 3678 | SGML) to simple data encoding mechanisms like configuration file formatting
|
|---|
| 3679 | (glade), spreadsheets (gnumeric), or even shorter lived documents such as
|
|---|
| 3680 | WebDAV where it is used to encode remote calls between a client and a
|
|---|
| 3681 | server.</p>

|
|---|
| 3775 |
|
|---|
| 3776 | <p>Note to people interested in building bindings, the API is formalized as
|
|---|
| 3777 | <a href="libxml2-api.xml">an XML API description file</a> which allows to
|
|---|
| 3778 | automate a large part of the Python bindings, this includes function
|
|---|
| 3779 | descriptions, enums, structures, typedefs, etc... The Python script used to
|
|---|
| 3780 | build the bindings is python/generator.py in the source distribution.</p>
|
|---|
| 3781 |
|
|---|
| 3782 | <p>To install the Python bindings there are 2 options:</p>
|
|---|
| 3783 | <ul>
|
|---|
| 3784 | <li>If you use an RPM based distribution, simply install the <a
|
|---|
| 3785 | href="http://rpmfind.net/linux/rpm2html/search.php?query=libxml2-python">libxml2-python
|
|---|
| 3786 | RPM</a> (and if needed the <a
|
|---|
| 3787 | href="http://rpmfind.net/linux/rpm2html/search.php?query=libxslt-python">libxslt-python
|
|---|
| 3788 | RPM</a>).</li>
|
|---|
| 3789 | <li>Otherwise use the <a href="ftp://xmlsoft.org/libxml2/python/">libxml2-python
|
|---|
| 3790 | module distribution</a> corresponding to your installed version of
|
|---|
| 3791 | libxml2 and libxslt. Note that to install it you will need both libxml2
|
|---|
| 3792 | and libxslt installed and run "python setup.py build install" in the
|
|---|
| 3793 | module tree.</li>
|
|---|
| 3794 | </ul>
|
|---|
| 3795 |
|
|---|
| 3796 | <p>The distribution includes a set of examples and regression tests for the
|
|---|
| 3797 | python bindings in the <code>python/tests</code> directory. Here are some
|
|---|
| 3798 | excerpts from those tests:</p>
|
|---|
| 3799 |
|
|---|
| 3800 | <h3>tst.py:</h3>
|
|---|
| 3801 |
|
|---|
| 3802 | <p>This is a basic test of the file interface and DOM navigation:</p>
|
|---|
| 3803 | <pre>import libxml2, sys
|
|---|
| 3804 |
|
|---|
| 3805 | doc = libxml2.parseFile("tst.xml")
|
|---|
| 3806 | if doc.name != "tst.xml":
|
|---|
| 3807 | print "doc.name failed"
|
|---|
| 3808 | sys.exit(1)
|
|---|
| 3809 | root = doc.children
|
|---|
| 3810 | if root.name != "doc":
|
|---|
| 3811 | print "root.name failed"
|
|---|
| 3812 | sys.exit(1)
|
|---|
| 3813 | child = root.children
|
|---|
| 3814 | if child.name != "foo":
|
|---|
| 3815 | print "child.name failed"
|
|---|
| 3816 | sys.exit(1)
|
|---|
| 3817 | doc.freeDoc()</pre>
|
|---|
| 3818 |
|
|---|
| 3819 | <p>The Python module is called libxml2; parseFile is the equivalent of
|
|---|
| 3820 | xmlParseFile (most of the bindings are automatically generated, and the xml
|
|---|
| 3821 | prefix is removed and the casing convention are kept). All node seen at the
|
|---|
| 3822 | binding level share the same subset of accessors:</p>
|
|---|
| 3823 | <ul>
|
|---|
| 3824 | <li><code>name</code> : returns the node name</li>
|
|---|
| 3825 | <li><code>type</code> : returns a string indicating the node type</li>
|
|---|
| 3826 | <li><code>content</code> : returns the content of the node, it is based on
|
|---|
| 3827 | xmlNodeGetContent() and hence is recursive.</li>
|
|---|
| 3828 | <li><code>parent</code> , <code>children</code>, <code>last</code>,
|
|---|
| 3829 | <code>next</code>, <code>prev</code>, <code>doc</code>,
|
|---|
| 3830 | <code>properties</code>: pointing to the associated element in the tree,
|
|---|
| 3831 | those may return None in case no such link exists.</li>
|
|---|
| 3832 | </ul>
|
|---|
| 3833 |
|
|---|
| 3834 | <p>Also note the need to explicitly deallocate documents with freeDoc() .
|
|---|
| 3835 | Reference counting for libxml2 trees would need quite a lot of work to
|
|---|
| 3836 | function properly, and rather than risk memory leaks if not implemented
|
|---|
| 3837 | correctly it sounds safer to have an explicit function to free a tree. The
|
|---|
| 3838 | wrapper python objects like doc, root or child are them automatically garbage
|
|---|
| 3839 | collected.</p>
|
|---|
| 3840 |
|
|---|
| 3841 | <h3>validate.py:</h3>
|
|---|
| 3842 |
|
|---|
| 3843 | <p>This test check the validation interfaces and redirection of error
|
|---|
| 3844 | messages:</p>
|
|---|
| 3845 | <pre>import libxml2
|
|---|
| 3846 |
|
|---|
| 3847 | #deactivate error messages from the validation
|
|---|
| 3848 | def noerr(ctx, str):
|
|---|
| 3849 | pass
|
|---|
| 3850 |
|
|---|
| 3851 | libxml2.registerErrorHandler(noerr, None)
|
|---|
| 3852 |
|
|---|
| 3853 | ctxt = libxml2.createFileParserCtxt("invalid.xml")
|
|---|
| 3854 | ctxt.validate(1)
|
|---|
| 3855 | ctxt.parseDocument()
|
|---|
| 3856 | doc = ctxt.doc()
|
|---|
| 3857 | valid = ctxt.isValid()
|
|---|
| 3858 | doc.freeDoc()
|
|---|
| 3859 | if valid != 0:
|
|---|
| 3860 | print "validity check failed"</pre>
|
|---|
| 3861 |
|
|---|
| 3862 | <p>The first thing to notice is the call to registerErrorHandler(), it
|
|---|
| 3863 | defines a new error handler global to the library. It is used to avoid seeing
|
|---|
| 3864 | the error messages when trying to validate the invalid document.</p>
|
|---|
| 3865 |
|
|---|
| 3866 | <p>The main interest of that test is the creation of a parser context with
|
|---|
| 3867 | createFileParserCtxt() and how the behaviour can be changed before calling
|
|---|
| 3868 | parseDocument() . Similarly the information resulting from the parsing phase
|
|---|
| 3869 | is also available using context methods.</p>
|
|---|
| 3870 |
|
|---|
| 3871 | <p>Contexts like nodes are defined as class and the libxml2 wrappers maps the
|
|---|
| 3872 | C function interfaces in terms of objects method as much as possible. The
|
|---|
| 3873 | best to get a complete view of what methods are supported is to look at the
|
|---|
| 3874 | libxml2.py module containing all the wrappers.</p>
|
|---|
| 3875 |
|
|---|
| 3876 | <h3>push.py:</h3>
|
|---|
| 3877 |
|
|---|
| 3878 | <p>This test show how to activate the push parser interface:</p>
|
|---|
| 3879 | <pre>import libxml2
|
|---|
| 3880 |
|
|---|
| 3881 | ctxt = libxml2.createPushParser(None, "<foo", 4, "test.xml")
|
|---|
| 3882 | ctxt.parseChunk("/>", 2, 1)
|
|---|
| 3883 | doc = ctxt.doc()
|
|---|
| 3884 |
|
|---|
| 3885 | doc.freeDoc()</pre>
|
|---|
| 3886 |
|
|---|
| 3887 | <p>The context is created with a special call based on the
|
|---|
| 3888 | xmlCreatePushParser() from the C library. The first argument is an optional
|
|---|
| 3889 | SAX callback object, then the initial set of data, the length and the name of
|
|---|
| 3890 | the resource in case URI-References need to be computed by the parser.</p>
|
|---|
| 3891 |
|
|---|
| 3892 | <p>Then the data are pushed using the parseChunk() method, the last call
|
|---|
| 3893 | setting the third argument terminate to 1.</p>
|
|---|
| 3894 |
|
|---|
| 3895 | <h3>pushSAX.py:</h3>
|
|---|
| 3896 |
|
|---|
| 3897 | <p>this test show the use of the event based parsing interfaces. In this case
|
|---|
| 3898 | the parser does not build a document, but provides callback information as
|
|---|
| 3899 | the parser makes progresses analyzing the data being provided:</p>
|
|---|
| 3900 | <pre>import libxml2
|
|---|
| 3901 | log = ""
|
|---|
| 3902 |
|
|---|
| 3903 | class callback:

|
|---|
| 3919 |

|---|
| 3920 | def characters(self, data):
|
|---|
| 3921 | global log
|
|---|

|---|
| 3925 | global log
|
|---|
| 3926 | log = log + "warning: %s:" % (msg)
|
|---|
| 3927 |
|
|---|
| 3928 | def error(self, msg):
|
|---|
| 3929 | global log
|
|---|
| 3930 | log = log + "error: %s:" % (msg)
|
|---|
| 3931 |
|

| 3932 | def fatalError(self, msg):
|
|---|

|
|---|

|
|---|
| 3935 |
|
|---|
| 3936 | handler = callback()
|
|---|
| 3937 |
|
|---|
| 3938 | ctxt = libxml2.createPushParser(handler, "<foo", 4, "test.xml")
|
|---|
| 3939 | chunk = " url='tst'>b"
|
|---|
| 3940 | ctxt.parseChunk(chunk, len(chunk), 0)
|
|---|
| 3941 | chunk = "ar</foo>"
|
|---|
| 3942 | ctxt.parseChunk(chunk, len(chunk), 1)
|
|---|
| 3943 |
|
|---|
| 3944 | reference = "startDocument:startElement foo {'url': 'tst'}:" + \
|

|

| 3947 | print "Error got: %s" % log
|
|---|
| 3948 | print "Expected: %s" % reference</pre>
|
|---|
| 3949 |
|
|---|
| 3950 | <p>The key object in that test is the handler, it provides a number of entry
|
|---|
| 3951 | points which can be called by the parser as it makes progresses to indicate
|
|---|
| 3952 | the information set obtained. The full set of callback is larger than what
|
|---|
| 3953 | the callback class in that specific example implements (see the SAX
|
|---|
| 3954 | definition for a complete list). The wrapper will only call those supplied by
|
|---|
| 3955 | the object when activated. The startElement receives the names of the element
|
|---|
| 3956 | and a dictionary containing the attributes carried by this element.</p>
|
|---|
| 3957 |
|
|---|
| 3958 | <p>Also note that the reference string generated from the callback shows a
|
|---|
| 3959 | single character call even though the string "bar" is passed to the parser

| 3982 | and node sets are returned as a tuple of libxml2 Python nodes wrappers. Like
|
|---|
| 3983 | the document, the XPath context need to be freed explicitly, also not that
|

| 3984 | the result of the XPath query may point back to the document tree and hence
|

| 4009 |
|

| 4022 |
|

| 4023 | <p>All the interfaces around the XPath parser(or rather evaluation) context

| 4027 | <h3>Memory debugging:</h3>
|
|---|
| 4028 |
|
|---|
| 4029 | <p>last but not least, all tests starts with the following prologue:</p>
|
|---|
| 4030 | <pre>#memory debug specific
|
|---|
| 4031 | libxml2.debugMemory(1)</pre>
|
|---|
| 4032 |
|
|---|
| 4033 | <p>and ends with the following epilogue:</p>
|
|---|
| 4034 | <pre>#memory debug specific
|
|---|
| 4035 | libxml2.cleanupParser()
|
|---|
| 4036 | if libxml2.debugMemory(1) == 0:
|
|---|
| 4037 | print "OK"
|
|---|
| 4038 | else:
|
|---|
| 4039 | print "Memory leak %d bytes" % (libxml2.debugMemory(1))
|
|---|
| 4040 | libxml2.dumpMemory()</pre>
|
|---|
| 4041 |
|
|---|
| 4042 | <p>Those activate the memory debugging interface of libxml2 where all
|
|---|
| 4043 | allocated block in the library are tracked. The prologue then cleans up the
|
|---|
| 4044 | library state and checks that all allocated memory has been freed. If not it
|
|---|
| 4045 | calls dumpMemory() which saves that list in a <code>.memdump</code> file.</p>

| 4047 | <h2><a name="architecture">libxml2 architecture</a></h2>
|
|---|
| 4048 |
|
|---|
| 4049 | <p>Libxml2 is made of multiple components; some of them are optional, and
|
|---|
| 4050 | most of the block interfaces are public. The main components are:</p>
|
|---|
| 4051 | <ul>
|
|---|
| 4052 | <li>an Input/Output layer</li>
|
|---|
| 4053 | <li>FTP and HTTP client layers (optional)</li>
|
|---|
| 4054 | <li>an Internationalization layer managing the encodings support</li>
|
|---|
| 4055 | <li>a URI module</li>
|
|---|
| 4056 | <li>the XML parser and its basic SAX interface</li>
|
|---|
| 4057 | <li>an HTML parser using the same SAX interface (optional)</li>
|

| 4058 | <li>a SAX tree module to build an in-memory DOM representation</li>
|
|---|
| 4059 | <li>a tree module to manipulate the DOM representation</li>
|
|---|
| 4060 | <li>a validation module using the DOM representation (optional)</li>

| 4072 | <h2><a name="tree">The tree output</a></h2>
|
|---|
| 4073 |
|
|---|
| 4074 | <p>The parser returns a tree built during the document analysis. The value
|
|---|
| 4075 | returned is an <strong>xmlDocPtr</strong> (i.e., a pointer to an
|
|---|
| 4076 | <strong>xmlDoc</strong> structure). This structure contains information such
|
|---|
| 4077 | as the file name, the document type, and a <strong>children</strong> pointer
|
|---|
| 4078 | which is the root of the document (or more exactly the first child under the
|
|---|
| 4079 | root which is the document). The tree is made of <strong>xmlNode</strong>s,
|
|---|
| 4080 | chained in double-linked lists of siblings and with a children<->parent
|
|---|
| 4081 | relationship. An xmlNode can also carry properties (a chain of xmlAttr
|
|---|
| 4082 | structures). An attribute may have a value which is a list of TEXT or
|
|---|
| 4083 | ENTITY_REF nodes.</p>
|
|---|
| 4084 |
|
|---|
| 4085 | <p>Here is an example (erroneous with respect to the XML spec since there

| 4090 | <p>In the source package there is a small program (not installed by default)
|
|---|
| 4091 | called <strong>xmllint</strong> which parses XML files given as argument and
|
|---|
| 4092 | prints them back as parsed. This is useful for detecting errors both in XML
|
|---|
| 4093 | code and in the XML parser itself. It has an option <strong>--debug</strong>

| 4128 | <h2><a name="interface">The SAX interface</a></h2>
|
|---|
| 4129 |
|
|---|
| 4130 | <p>Sometimes the DOM tree output is just too large to fit reasonably into
|
|---|
| 4131 | memory. In that case (and if you don't expect to save back the XML document
|
|---|
| 4132 | loaded using libxml), it's better to use the SAX interface of libxml. SAX is
|
|---|
| 4133 | a <strong>callback-based interface</strong> to the parser. Before parsing,
|
|---|
| 4134 | the application layer registers a customized set of callbacks which are
|
|---|
| 4135 | called by the library as it progresses through the XML input.</p>
|
|---|
| 4136 |
|
|---|
| 4137 | <p>To get more detailed step-by-step guidance on using the SAX interface of
|
|---|
| 4138 | libxml, see the <a

|
|---|
| 4142 |
|
|---|
| 4143 | <p>You can debug the SAX behaviour by using the <strong>testSAX</strong>
|
|---|
| 4144 | program located in the gnome-xml module (it's usually not shipped in the
|
|---|
| 4145 | binary packages of libxml, but you can find it in the tar source
|
|---|
| 4146 | distribution). Here is the sequence of callbacks that would be reported by
|
|---|
| 4147 | testSAX when parsing the example XML document shown earlier:</p>

|
|---|
| 4208 |
|
|---|
| 4209 | <p>Well what is validation and what is a DTD ?</p>
|
|---|
| 4210 |
|
|---|
| 4211 | <p>DTD is the acronym for Document Type Definition. This is a description of
|
|---|
| 4212 | the content for a family of XML files. This is part of the XML 1.0
|
|---|
| 4213 | specification, and allows one to describe and verify that a given document
|
|---|
| 4214 | instance conforms to the set of rules detailing its structure and content.</p>
|
|---|
| 4215 |
|
|---|
| 4216 | <p>Validation is the process of checking a document against a DTD (more
|
|---|
| 4217 | generally against a set of construction rules).</p>
|
|---|
| 4218 |
|
|---|
| 4219 | <p>The validation process and building DTDs are the two most difficult parts
|
|---|
| 4220 | of the XML life cycle. Briefly a DTD defines all the possible elements to be
|
|---|
| 4221 | found within your document, what is the formal shape of your document tree
|
|---|
| 4222 | (by defining the allowed content of an element; either text, a regular
|
|---|
| 4223 | expression for the allowed list of children, or mixed content i.e. both text
|
|---|
| 4224 | and children). The DTD also defines the valid attributes for all elements and
|
|---|
| 4225 | the types of those attributes.</p>

|
|---|
| 4243 |
|
|---|
| 4244 | <p>Writing DTDs can be done in many ways. The rules to build them if you need
|
|---|
| 4245 | something permanent or something which can evolve over time can be radically
|
|---|
| 4246 | different. Really complex DTDs like DocBook ones are flexible but quite
|
|---|
| 4247 | harder to design. I will just focus on DTDs for a formats with a fixed simple
|
|---|
| 4248 | structure. It is just a set of basic rules, and definitely not exhaustive nor
|
|---|
| 4249 | usable for complex DTD design.</p>

|

|
|---|
| 4253 | <p>Assuming the top element of the document is <code>spec</code> and the dtd
|
|---|
| 4254 | is placed in the file <code>mydtd</code> in the subdirectory
|
|---|
| 4255 | <code>dtds</code> of the directory from where the document were loaded:</p>
|

| 4257 | <p><code><!DOCTYPE spec SYSTEM "dtds/mydtd"></code></p>

|
|---|
| 4259 | <p>Notes:</p>
|
|---|
| 4260 | <ul>
|
|---|
| 4261 | <li>The system string is actually an URI-Reference (as defined in <a
|
|---|
| 4262 | href="http://www.ietf.org/rfc/rfc2396.txt">RFC 2396</a>) so you can use a
|
|---|
| 4263 | full URL string indicating the location of your DTD on the Web. This is a
|
|---|
| 4264 | really good thing to do if you want others to validate your document.</li>
|
|---|
| 4265 | <li>It is also possible to associate a <code>PUBLIC</code> identifier (a
|
|---|
| 4266 | magic string) so that the DTD is looked up in catalogs on the client side
|
|---|
| 4267 | without having to locate it on the web.</li>
|
|---|
| 4268 | <li>A DTD contains a set of element and attribute declarations, but they
|
|---|
| 4269 | don't define what the root of the document should be. This is explicitly
|
|---|
| 4270 | told to the parser/validator as the first element of the
|

| 4280 | <p>It also expresses that the spec element contains one <code>front</code>,
|
|---|
| 4281 | one <code>body</code> and one optional <code>back</code> children elements in
|
|---|
| 4282 | this order. The declaration of one element of the structure and its content
|
|---|
| 4283 | are done in a single declaration. Similarly the following declares
|
|---|
| 4284 | <code>div1</code> elements:</p>
|
|---|
| 4285 |
|
|---|
| 4286 | <p><code><!ELEMENT div1 (head, (p | list | note)*, div2?)></code></p>
|
|---|
| 4287 |
|
|---|
| 4288 | <p>which means div1 contains one <code>head</code> then a series of optional
|
|---|
| 4289 | <code>p</code>, <code>list</code>s and <code>note</code>s and then an
|
|---|
| 4290 | optional <code>div2</code>. And last but not least an element can contain
|
|---|
| 4291 | text:</p>
|
|---|
| 4292 |
|
|---|
| 4293 | <p><code><!ELEMENT b (#PCDATA)></code></p>
|
|---|
| 4294 |
|
|---|
| 4295 | <p><code>b</code> contains text or being of mixed content (text and elements
|
|---|
| 4296 | in no particular order):</p>
|
|---|
| 4297 |
|
|---|
| 4298 | <p><code><!ELEMENT p (#PCDATA|a|ul|b|i|em)*></code></p>
|
|---|
| 4299 |
|
|---|
| 4300 | <p><code>p </code>can contain text or <code>a</code>, <code>ul</code>,
|
|---|
| 4301 | <code>b</code>, <code>i </code>or <code>em</code> elements in no particular
|
|---|
| 4302 | order.</p>

| 4304 | <h4><a name="Declaring1">Declaring attributes</a>:</h4>
|
|---|
| 4305 |
|
|---|
| 4306 | <p>Again the attributes declaration includes their content definition:</p>
|

| 4307 |
|
|---|
| 4308 | <p><code><!ATTLIST termdef name CDATA #IMPLIED></code></p>
|
|---|
| 4309 |
|
|---|
| 4310 | <p>means that the element <code>termdef</code> can have a <code>name</code>
|
|---|
| 4311 | attribute containing text (<code>CDATA</code>) and which is optional
|
|---|
| 4312 | (<code>#IMPLIED</code>). The attribute value can also be defined within a
|
|---|
| 4313 | set:</p>
|
|---|
| 4314 |
|
|---|
| 4315 | <p><code><!ATTLIST list type (bullets|ordered|glossary)
|
|---|
| 4316 | "ordered"></code></p>
|
|---|
| 4317 |
|
|---|
| 4318 | <p>means <code>list</code> element have a <code>type</code> attribute with 3
|
|---|
| 4319 | allowed values "bullets", "ordered" or "glossary" and which default to
|
|---|
| 4320 | "ordered" if the attribute is not explicitly specified.</p>
|
|---|
| 4321 |
|
|---|
| 4322 | <p>The content type of an attribute can be text (<code>CDATA</code>),
|
|---|
| 4323 | anchor/reference/references
|
|---|
| 4324 | (<code>ID</code>/<code>IDREF</code>/<code>IDREFS</code>), entity(ies)
|
|---|
| 4325 | (<code>ENTITY</code>/<code>ENTITIES</code>) or name(s)
|
|---|
| 4326 | (<code>NMTOKEN</code>/<code>NMTOKENS</code>). The following defines that a
|
|---|
| 4327 | <code>chapter</code> element can have an optional <code>id</code> attribute
|
|---|
| 4328 | of type <code>ID</code>, usable for reference from attribute of type
|
|---|
| 4329 | IDREF:</p>
|
|---|
| 4330 |
|
|---|
| 4331 | <p><code><!ATTLIST chapter id ID #IMPLIED></code></p>
|
|---|
| 4332 |
|
|---|
| 4333 | <p>The last value of an attribute definition can be <code>#REQUIRED
|
|---|
| 4334 | </code>meaning that the attribute has to be given, <code>#IMPLIED</code>
|
|---|
| 4335 | meaning that it is optional, or the default value (possibly prefixed by
|
|---|
| 4336 | <code>#FIXED</code> if it is the only allowed).</p>
|
|---|
| 4337 |
|
|---|
| 4338 | <p>Notes:</p>
|
|---|
| 4339 | <ul>
|
|---|
| 4340 | <li>Usually the attributes pertaining to a given element are declared in a
|
|---|
| 4341 | single expression, but it is just a convention adopted by a lot of DTD
|
|---|
| 4342 | writers:
|
|---|
| 4343 | <pre><!ATTLIST termdef
|
|---|
| 4344 | id ID #REQUIRED
|
|---|
| 4345 | name CDATA #IMPLIED></pre>
|
|---|
| 4346 | <p>The previous construct defines both <code>id</code> and
|
|---|
| 4347 | <code>name</code> attributes for the element <code>termdef</code>.</p>

|

| 4352 |
|
|---|
| 4353 | <p>The directory <code>test/valid/dtds/</code> in the libxml2 distribution
|
|---|
| 4354 | contains some complex DTD examples. The example in the file
|
|---|
| 4355 | <code>test/valid/dia.xml</code> shows an XML file where the simple DTD is
|
|---|
| 4356 | directly included within the document.</p>
|
|---|
| 4357 |
|
|---|
| 4358 | <h3><a name="validate1">How to validate</a></h3>
|
|---|
| 4359 |
|
|---|
| 4360 | <p>The simplest way is to use the xmllint program included with libxml. The
|
|---|
| 4361 | <code>--valid</code> option turns-on validation of the files given as input.
|
|---|
| 4362 | For example the following validates a copy of the first revision of the XML
|
|---|
| 4363 | 1.0 specification:</p>
|
|---|
| 4364 |
|
|---|
| 4365 | <p><code>xmllint --valid --noout test/valid/REC-xml-19980210.xml</code></p>
|
|---|
| 4366 |
|
|---|
| 4367 | <p>the -- noout is used to disable output of the resulting tree.</p>
|
|---|
| 4368 |
|
|---|
| 4369 | <p>The <code>--dtdvalid dtd</code> allows validation of the document(s)
|
|---|
| 4370 | against a given DTD.</p>
|
|---|
| 4371 |
|
|---|
| 4372 | <p>Libxml2 exports an API to handle DTDs and validation, check the <a
|
|---|
| 4373 | href="http://xmlsoft.org/html/libxml-valid.html">associated
|
|---|
| 4374 | description</a>.</p>

| 4376 | <h3><a name="Other1">Other resources</a></h3>
|

| 4378 | <p>DTDs are as old as SGML. So there may be a number of examples on-line, I
|

| 4379 | will just list one for now, others pointers welcome:</p>

|
|---|
| 4383 |
|
|---|
| 4384 | <p>I suggest looking at the examples found under test/valid/dtd and any of
|
|---|
| 4385 | the large number of books available on XML. The dia example in test/valid
|

|
|---|
| 4404 | <p>The module <code><a
|
|---|
| 4405 | href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlmemory.h</a></code>
|
|---|
| 4406 | provides the interfaces to the libxml2 memory system:</p>
|
|---|
| 4407 | <ul>
|
|---|
| 4408 | <li>libxml2 does not use the libc memory allocator directly but xmlFree(),
|
|---|
| 4409 | xmlMalloc() and xmlRealloc()</li>
|
|---|
| 4410 | <li>those routines can be reallocated to a specific set of routine, by
|
|---|
| 4411 | default the libc ones i.e. free(), malloc() and realloc()</li>
|
|---|
| 4412 | <li>the xmlmemory.c module includes a set of debugging routine</li>
|
|---|
| 4413 | </ul>
|
|---|
| 4414 |
|
|---|
| 4415 | <h3><a name="setting">Setting libxml2 set of memory routines</a></h3>
|
|---|
| 4416 |
|
|---|
| 4417 | <p>It is sometimes useful to not use the default memory allocator, either for
|
|---|
| 4418 | debugging, analysis or to implement a specific behaviour on memory management
|
|---|
| 4419 | (like on embedded systems). Two function calls are available to do so:</p>
|
|---|
| 4420 | <ul>
|
|---|
| 4421 | <li><a href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemGet
|
|---|
| 4422 | ()</a> which return the current set of functions in use by the parser</li>
|
|---|
| 4423 | <li><a
|
|---|
| 4424 | href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemSetup()</a>
|
|---|
| 4425 | which allow to set up a new set of memory allocation functions</li>
|
|---|
| 4426 | </ul>
|
|---|
| 4427 |
|
|---|
| 4428 | <p>Of course a call to xmlMemSetup() should probably be done before calling
|
|---|
| 4429 | any other libxml2 routines (unless you are sure your allocations routines are
|
|---|
| 4430 | compatibles).</p>
|
|---|
| 4431 |
|
|---|
| 4432 | <h3><a name="cleanup">Cleaning up after using the library</a></h3>
|
|---|
| 4433 |
|
|---|
| 4434 | <p>Libxml2 is not stateless, there is a few set of memory structures needing
|
|---|
| 4435 | allocation before the parser is fully functional (some encoding structures
|
|---|
| 4436 | for example). This also mean that once parsing is finished there is a tiny
|
|---|
| 4437 | amount of memory (a few hundred bytes) which can be recollected if you don't
|
|---|
| 4438 | reuse the library or any document built with it:</p>
|
|---|
| 4439 | <ul>
|
|---|
| 4440 | <li><a href="http://xmlsoft.org/html/libxml-parser.html">xmlCleanupParser
|
|---|
| 4441 | ()</a> is a centralized routine to free the library state and data. Note
|
|---|
| 4442 | that it won't deallocate any produced tree if any (use the xmlFreeDoc()
|
|---|
| 4443 | and related routines for this). This should be called only when the library
|
|---|
| 4444 | is not used anymore.</li>
|
|---|
| 4445 | <li><a href="http://xmlsoft.org/html/libxml-parser.html">xmlInitParser
|
|---|
| 4446 | ()</a> is the dual routine allowing to preallocate the parsing state
|
|---|
| 4447 | which can be useful for example to avoid initialization reentrancy
|
|---|
| 4448 | problems when using libxml2 in multithreaded applications</li>
|
|---|
| 4449 | </ul>
|
|---|
| 4450 |
|
|---|
| 4451 | <p>Generally xmlCleanupParser() is safe assuming no parsing is ongoing and
|
|---|
| 4452 | no document is still being used, if needed the state will be rebuild at the
|
|---|
| 4453 | next invocation of parser routines (or by xmlInitParser()), but be careful
|
|---|
| 4454 | of the consequences in multithreaded applications.</p>

|
|---|
| 4456 | <h3><a name="Debugging">Debugging routines</a></h3>
|
|---|
| 4457 |
|
|---|
| 4458 | <p>When configured using --with-mem-debug flag (off by default), libxml2 uses
|
|---|
| 4459 | a set of memory allocation debugging routines keeping track of all allocated
|
|---|
| 4460 | blocks and the location in the code where the routine was called. A couple of
|
|---|
| 4461 | other debugging routines allow to dump the memory allocated infos to a file
|
|---|
| 4462 | or call a specific routine when a given block number is allocated:</p>
|
|---|
| 4463 | <ul>
|
|---|
| 4464 | <li><a
|
|---|
| 4465 | href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMallocLoc()</a>
|
|---|
| 4466 | <a
|
|---|
| 4467 | href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlReallocLoc()</a>
|
|---|
| 4468 | and <a
|
|---|
| 4469 | href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemStrdupLoc()</a>
|
|---|
| 4470 | are the memory debugging replacement allocation routines</li>
|
|---|
| 4471 | <li><a href="http://xmlsoft.org/html/libxml-xmlmemory.html">xmlMemoryDump
|
|---|
| 4472 | ()</a> dumps all the information about the allocated memory block lefts
|
|---|
| 4473 | in the <code>.memdump</code> file</li>
|
|---|
| 4474 | </ul>
|
|---|
| 4475 |
|
|---|
| 4476 | <p>When developing libxml2 memory debug is enabled, the tests programs call
|
|---|
| 4477 | xmlMemoryDump () and the "make test" regression tests will check for any
|
|---|
| 4478 | memory leak during the full regression test sequence, this helps a lot
|
|---|
| 4479 | ensuring that libxml2 does not leak memory and bullet proof memory
|
|---|
| 4480 | allocations use (some libc implementations are known to be far too permissive
|
|---|
| 4481 | resulting in major portability problems!).</p>
|
|---|
| 4482 |
|
|---|
| 4483 | <p>If the .memdump reports a leak, it displays the allocation function and
|
|---|
| 4484 | also tries to give some information about the content and structure of the
|
|---|
| 4485 | allocated blocks left. This is sufficient in most cases to find the culprit,
|
|---|
| 4486 | but not always. Assuming the allocation problem is reproducible, it is
|
|---|
| 4487 | possible to find more easily:</p>
|
|---|
| 4488 | <ol>
|
|---|
| 4489 | <li>write down the block number xxxx not allocated</li>
|
|---|
| 4490 | <li>export the environment variable XML_MEM_BREAKPOINT=xxxx , the easiest
|
|---|
| 4491 | when using GDB is to simply give the command
|
|---|
| 4492 | <p><code>set environment XML_MEM_BREAKPOINT xxxx</code></p>
|
|---|
| 4493 | <p>before running the program.</p>
|
|---|
| 4494 | </li>
|
|---|
| 4495 | <li>run the program under a debugger and set a breakpoint on
|
|---|
| 4496 | xmlMallocBreakpoint() a specific function called when this precise block
|
|---|
| 4497 | is allocated</li>
|
|---|
| 4498 | <li>when the breakpoint is reached you can then do a fine analysis of the
|
|---|
| 4499 | allocation an step to see the condition resulting in the missing
|
|---|
| 4500 | deallocation.</li>
|
|---|
| 4501 | </ol>
|
|---|
| 4502 |
|
|---|
| 4503 | <p>I used to use a commercial tool to debug libxml2 memory problems but after
|
|---|
| 4504 | noticing that it was not detecting memory leaks that simple mechanism was
|
|---|
| 4505 | used and proved extremely efficient until now. Lately I have also used <a
|
|---|
| 4506 | href="http://developer.kde.org/~sewardj/">valgrind</a> with quite some
|
|---|
| 4507 | success, it is tied to the i386 architecture since it works by emulating the
|
|---|
| 4508 | processor and instruction set, it is slow but extremely efficient, i.e. it
|
|---|
| 4509 | spot memory usage errors in a very precise way.</p>
|
|---|
| 4510 |
|
|---|
| 4511 | <h3><a name="General4">General memory requirements</a></h3>
|
|---|
| 4512 |
|
|---|
| 4513 | <p>How much libxml2 memory require ? It's hard to tell in average it depends
|
|---|
| 4514 | of a number of things:</p>
|
|---|
| 4515 | <ul>
|
|---|
| 4516 | <li>the parser itself should work in a fixed amount of memory, except for
|
|---|
| 4517 | information maintained about the stacks of names and entities locations.
|
|---|
| 4518 | The I/O and encoding handlers will probably account for a few KBytes.
|
|---|
| 4519 | This is true for both the XML and HTML parser (though the HTML parser
|
|---|
| 4520 | need more state).</li>
|
|---|
| 4521 | <li>If you are generating the DOM tree then memory requirements will grow
|
|---|
| 4522 | nearly linear with the size of the data. In general for a balanced
|
|---|
| 4523 | textual document the internal memory requirement is about 4 times the
|
|---|
| 4524 | size of the UTF8 serialization of this document (example the XML-1.0
|
|---|
| 4525 | recommendation is a bit more of 150KBytes and takes 650KBytes of main
|
|---|
| 4526 | memory when parsed). Validation will add a amount of memory required for
|
|---|
| 4527 | maintaining the external Dtd state which should be linear with the
|
|---|
| 4528 | complexity of the content model defined by the Dtd</li>
|
|---|
| 4529 | <li>If you need to work with fixed memory requirements or don't need the
|
|---|
| 4530 | full DOM tree then using the <a href="xmlreader.html">xmlReader
|
|---|
| 4531 | interface</a> is probably the best way to proceed, it still allows to
|
|---|
| 4532 | validate or operate on subset of the tree if needed.</li>
|
|---|
| 4533 | <li>If you don't care about the advanced features of libxml2 like
|
|---|
| 4534 | validation, DOM, XPath or XPointer, don't use entities, need to work with
|
|---|
| 4535 | fixed memory requirements, and try to get the fastest parsing possible
|
|---|
| 4536 | then the SAX interface should be used, but it has known restrictions.</li>
|
|---|
| 4537 | </ul>

| 4540 | <h3><a name="Compacting">Returning memory to the kernel</a></h3>
|
|---|
| 4541 |
|
|---|
| 4542 | <p>You may encounter that your process using libxml2 does not have a
|
|---|
| 4543 | reduced memory usage although you freed the trees. This is because
|
|---|
| 4544 | libxml2 allocates memory in a number of small chunks. When freeing one
|
|---|
| 4545 | of those chunks, the OS may decide that giving this little memory back
|
|---|
| 4546 | to the kernel will cause too much overhead and delay the operation. As
|
|---|
| 4547 | all chunks are this small, they get actually freed but not returned to
|
|---|
| 4548 | the kernel. On systems using glibc, there is a function call
|
|---|
| 4549 | "malloc_trim" from malloc.h which does this missing operation (note that
|
|---|
| 4550 | it is allowed to fail). Thus, after freeing your tree you may simply try
|
|---|
| 4551 | "malloc_trim(0);" to really get the memory back. If your OS does not
|
|---|
| 4552 | provide malloc_trim, try searching for a similar function.</p>

| 4581 | <h3><a name="What">What does internationalization support mean ?</a></h3>
|
|---|
| 4582 |
|
|---|
| 4583 | <p>XML was designed from the start to allow the support of any character set
|
|---|
| 4584 | by using Unicode. Any conformant XML parser has to support the UTF-8 and
|
|---|
| 4585 | UTF-16 default encodings which can both express the full unicode ranges. UTF8
|
|---|
| 4586 | is a variable length encoding whose greatest points are to reuse the same
|
|---|
| 4587 | encoding for ASCII and to save space for Western encodings, but it is a bit
|
|---|
| 4588 | more complex to handle in practice. UTF-16 use 2 bytes per character (and
|
|---|
| 4589 | sometimes combines two pairs), it makes implementation easier, but looks a
|
|---|
| 4590 | bit overkill for Western languages encoding. Moreover the XML specification
|
|---|
| 4591 | allows the document to be encoded in other encodings at the condition that
|
|---|
| 4592 | they are clearly labeled as such. For example the following is a wellformed
|
|---|
| 4593 | XML document encoded in ISO-8859-1 and using accentuated letters that we
|
|---|
| 4594 | French like for both markup and content:</p>
|
|---|
| 4595 | <pre><?xml version="1.0" encoding="ISO-8859-1"?>
|
|---|
| 4596 | <très>là </très></pre>
|
|---|
| 4597 |
|
|---|
| 4598 | <p>Having internationalization support in libxml2 means the following:</p>
|
|---|
| 4599 | <ul>
|
|---|
| 4600 | <li>the document is properly parsed</li>
|
|---|
| 4601 | <li>information about it's encoding is saved</li>
|
|---|
| 4602 | <li>it can be modified</li>
|
|---|
| 4603 | <li>it can be saved in its original encoding</li>
|
|---|
| 4604 | <li>it can also be saved in another encoding supported by libxml2 (for
|
|---|
| 4605 | example straight UTF8 or even an ASCII form)</li>
|
|---|
| 4606 | </ul>
|
|---|
| 4607 |
|
|---|
| 4608 | <p>Another very important point is that the whole libxml2 API, with the
|
|---|
| 4609 | exception of a few routines to read with a specific encoding or save to a
|
|---|
| 4610 | specific encoding, is completely agnostic about the original encoding of the
|
|---|
| 4611 | document.</p>
|
|---|
| 4612 |
|
|---|
| 4613 | <p>It should be noted too that the HTML parser embedded in libxml2 now obey
|
|---|
| 4614 | the same rules too, the following document will be (as of 2.2.2) handled in
|
|---|
| 4615 | an internationalized fashion by libxml2 too:</p>

| 4626 | <h3><a name="internal">The internal encoding, how and why</a></h3>
|
|---|
| 4627 |
|
|---|
| 4628 | <p>One of the core decisions was to force all documents to be converted to a
|
|---|
| 4629 | default internal encoding, and that encoding to be UTF-8, here are the
|
|---|
| 4630 | rationales for those choices:</p>
|
|---|
| 4631 | <ul>
|
|---|
| 4632 | <li>keeping the native encoding in the internal form would force the libxml
|
|---|
| 4633 | users (or the code associated) to be fully aware of the encoding of the
|
|---|
| 4634 | original document, for examples when adding a text node to a document,
|
|---|
| 4635 | the content would have to be provided in the document encoding, i.e. the
|
|---|
| 4636 | client code would have to check it before hand, make sure it's conformant
|
|---|
| 4637 | to the encoding, etc ... Very hard in practice, though in some specific
|
|---|
| 4638 | cases this may make sense.</li>
|
|---|
| 4639 | <li>the second decision was which encoding. From the XML spec only UTF8 and
|
|---|
| 4640 | UTF16 really makes sense as being the two only encodings for which there
|
|---|
| 4641 | is mandatory support. UCS-4 (32 bits fixed size encoding) could be
|
|---|
| 4642 | considered an intelligent choice too since it's a direct Unicode mapping
|
|---|
| 4643 | support. I selected UTF-8 on the basis of efficiency and compatibility
|
|---|
| 4644 | with surrounding software:
|
|---|
| 4645 | <ul>
|
|---|
| 4646 | <li>UTF-8 while a bit more complex to convert from/to (i.e. slightly
|
|---|
| 4647 | more costly to import and export CPU wise) is also far more compact
|
|---|
| 4648 | than UTF-16 (and UCS-4) for a majority of the documents I see it used
|
|---|
| 4649 | for right now (RPM RDF catalogs, advogato data, various configuration
|
|---|
| 4650 | file formats, etc.) and the key point for today's computer
|
|---|
| 4651 | architecture is efficient uses of caches. If one nearly double the
|
|---|
| 4652 | memory requirement to store the same amount of data, this will trash
|
|---|
| 4653 | caches (main memory/external caches/internal caches) and my take is
|
|---|
| 4654 | that this harms the system far more than the CPU requirements needed
|
|---|
| 4655 | for the conversion to UTF-8</li>
|
|---|
| 4656 | <li>Most of libxml2 version 1 users were using it with straight ASCII
|
|---|
| 4657 | most of the time, doing the conversion with an internal encoding
|
|---|
| 4658 | requiring all their code to be rewritten was a serious show-stopper
|
|---|
| 4659 | for using UTF-16 or UCS-4.</li>
|
|---|
| 4660 | <li>UTF-8 is being used as the de-facto internal encoding standard for
|
|---|
| 4661 | related code like the <a href="http://www.pango.org/">pango</a>
|
|---|
| 4662 | upcoming Gnome text widget, and a lot of Unix code (yet another place
|
|---|
| 4663 | where Unix programmer base takes a different approach from Microsoft
|
|---|
| 4664 | - they are using UTF-16)</li>
|
|---|
| 4665 | </ul>
|
|---|
| 4666 | </li>
|
|---|
| 4667 | </ul>
|
|---|
| 4668 |
|
|---|
| 4669 | <p>What does this mean in practice for the libxml2 user:</p>
|
|---|
| 4670 | <ul>
|
|---|
| 4671 | <li>xmlChar, the libxml2 data type is a byte, those bytes must be assembled
|
|---|
| 4672 | as UTF-8 valid strings. The proper way to terminate an xmlChar * string
|
|---|
| 4673 | is simply to append 0 byte, as usual.</li>
|
|---|
| 4674 | <li>One just need to make sure that when using chars outside the ASCII set,
|
|---|
| 4675 | the values has been properly converted to UTF-8</li>
|
|---|
| 4676 | </ul>
|
|---|
| 4677 |
|
|---|
| 4678 | <h3><a name="implemente">How is it implemented ?</a></h3>
|
|---|
| 4679 |
|
|---|
| 4680 | <p>Let's describe how all this works within libxml, basically the I18N
|
|---|
| 4681 | (internationalization) support get triggered only during I/O operation, i.e.
|
|---|
| 4682 | when reading a document or saving one. Let's look first at the reading
|
|---|
| 4683 | sequence:</p>
|
|---|
| 4684 | <ol>
|
|---|
| 4685 | <li>when a document is processed, we usually don't know the encoding, a
|
|---|
| 4686 | simple heuristic allows to detect UTF-16 and UCS-4 from encodings where
|
|---|
| 4687 | the ASCII range (0-0x7F) maps with ASCII</li>
|
|---|
| 4688 | <li>the xml declaration if available is parsed, including the encoding
|
|---|
| 4689 | declaration. At that point, if the autodetected encoding is different
|
|---|
| 4690 | from the one declared a call to xmlSwitchEncoding() is issued.</li>
|
|---|
| 4691 | <li>If there is no encoding declaration, then the input has to be in either
|
|---|
| 4692 | UTF-8 or UTF-16, if it is not then at some point when processing the
|
|---|
| 4693 | input, the converter/checker of UTF-8 form will raise an encoding error.
|
|---|
| 4694 | You may end-up with a garbled document, or no document at all ! Example:
|
|---|
| 4695 | <pre>~/XML -> ./xmllint err.xml
|
|---|
| 4696 | err.xml:1: error: Input is not proper UTF-8, indicate encoding !
|
|---|
| 4697 | <très>là </très>
|
|---|
| 4698 | ^
|
|---|
| 4699 | err.xml:1: error: Bytes: 0xE8 0x73 0x3E 0x6C
|
|---|
| 4700 | <très>là </très>
|
|---|
| 4701 | ^</pre>
|
|---|
| 4702 | </li>
|
|---|
| 4703 | <li>xmlSwitchEncoding() does an encoding name lookup, canonicalize it, and
|
|---|
| 4704 | then search the default registered encoding converters for that encoding.
|
|---|
| 4705 | If it's not within the default set and iconv() support has been compiled
|
|---|
| 4706 | it, it will ask iconv for such an encoder. If this fails then the parser
|
|---|
| 4707 | will report an error and stops processing:
|
|---|
| 4708 | <pre>~/XML -> ./xmllint err2.xml
|
|---|
| 4709 | err2.xml:1: error: Unsupported encoding UnsupportedEnc
|
|---|
| 4710 | <?xml version="1.0" encoding="UnsupportedEnc"?>
|
|---|
| 4711 | ^</pre>
|
|---|
| 4712 | </li>
|
|---|
| 4713 | <li>From that point the encoder processes progressively the input (it is
|
|---|
| 4714 | plugged as a front-end to the I/O module) for that entity. It captures
|
|---|
| 4715 | and converts on-the-fly the document to be parsed to UTF-8. The parser
|
|---|
| 4716 | itself just does UTF-8 checking of this input and process it
|
|---|
| 4717 | transparently. The only difference is that the encoding information has
|
|---|
| 4718 | been added to the parsing context (more precisely to the input
|
|---|
| 4719 | corresponding to this entity).</li>
|
|---|
| 4720 | <li>The result (when using DOM) is an internal form completely in UTF-8
|
|---|
| 4721 | with just an encoding information on the document node.</li>
|
|---|
| 4722 | </ol>
|
|---|
| 4723 |
|
|---|
| 4724 | <p>Ok then what happens when saving the document (assuming you
|
|---|
| 4725 | collected/built an xmlDoc DOM like structure) ? It depends on the function
|
|---|
| 4726 | called, xmlSaveFile() will just try to save in the original encoding, while
|
|---|
| 4727 | xmlSaveFileTo() and xmlSaveFileEnc() can optionally save to a given
|
|---|
| 4728 | encoding:</p>
|
|---|
| 4729 | <ol>
|
|---|
| 4730 | <li>if no encoding is given, libxml2 will look for an encoding value
|
|---|
| 4731 | associated to the document and if it exists will try to save to that
|
|---|
| 4732 | encoding,
|
|---|
| 4733 | <p>otherwise everything is written in the internal form, i.e. UTF-8</p>
|
|---|
| 4734 | </li>
|
|---|
| 4735 | <li>so if an encoding was specified, either at the API level or on the
|
|---|
| 4736 | document, libxml2 will again canonicalize the encoding name, lookup for a
|
|---|
| 4737 | converter in the registered set or through iconv. If not found the
|
|---|
| 4738 | function will return an error code</li>
|
|---|
| 4739 | <li>the converter is placed before the I/O buffer layer, as another kind of
|
|---|
| 4740 | buffer, then libxml2 will simply push the UTF-8 serialization to through
|
|---|
| 4741 | that buffer, which will then progressively be converted and pushed onto
|
|---|
| 4742 | the I/O layer.</li>
|
|---|
| 4743 | <li>It is possible that the converter code fails on some input, for example
|
|---|
| 4744 | trying to push an UTF-8 encoded Chinese character through the UTF-8 to
|
|---|
| 4745 | ISO-8859-1 converter won't work. Since the encoders are progressive they
|
|---|
| 4746 | will just report the error and the number of bytes converted, at that
|
|---|
| 4747 | point libxml2 will decode the offending character, remove it from the
|
|---|
| 4748 | buffer and replace it with the associated charRef encoding &#123; and
|
|---|
| 4749 | resume the conversion. This guarantees that any document will be saved
|
|---|
| 4750 | without losses (except for markup names where this is not legal, this is
|
|---|
| 4751 | a problem in the current version, in practice avoid using non-ascii
|
|---|
| 4752 | characters for tag or attribute names). A special "ascii" encoding name
|
|---|
| 4753 | is used to save documents to a pure ascii form can be used when
|
|---|
| 4754 | portability is really crucial</li>
|
|---|
| 4755 | </ol>
|
|---|
| 4756 |
|
|---|
| 4757 | <p>Here are a few examples based on the same test document and assumin a
|
|---|
| 4758 | terminal using ISO-8859-1 as the text encoding:</p>
|
|---|
| 4759 | <pre>~/XML -> ./xmllint isolat1
|
|---|
| 4760 | <?xml version="1.0" encoding="ISO-8859-1"?>
|
|---|
| 4761 | <très>là </très>
|
|---|
| 4762 | ~/XML -> ./xmllint --encode UTF-8 isolat1
|
|---|
| 4763 | <?xml version="1.0" encoding="UTF-8"?>
|
|---|
| 4764 | <très>là </très>
|
|---|
| 4765 | ~/XML -> </pre>
|
|---|
| 4766 |
|
|---|
| 4767 | <p>The same processing is applied (and reuse most of the code) for HTML I18N
|
|---|
| 4768 | processing. Looking up and modifying the content encoding is a bit more
|
|---|
| 4769 | difficult since it is located in a <meta> tag under the <head>,
|
|---|
| 4770 | so a couple of functions htmlGetMetaEncoding() and htmlSetMetaEncoding() have
|
|---|
| 4771 | been provided. The parser also attempts to switch encoding on the fly when
|
|---|
| 4772 | detecting such a tag on input. Except for that the processing is the same
|
|---|
| 4773 | (and again reuses the same code).</p>
|
|---|
| 4774 |
|
|---|
| 4775 | <h3><a name="Default">Default supported encodings</a></h3>
|
|---|
| 4776 |
|
|---|
| 4777 | <p>libxml2 has a set of default converters for the following encodings
|
|---|
| 4778 | (located in encoding.c):</p>
|
|---|
| 4779 | <ol>
|
|---|
| 4780 | <li>UTF-8 is supported by default (null handlers)</li>
|
|---|
| 4781 | <li>UTF-16, both little and big endian</li>
|
|---|
| 4782 | <li>ISO-Latin-1 (ISO-8859-1) covering most western languages</li>
|
|---|
| 4783 | <li>ASCII, useful mostly for saving</li>
|
|---|
| 4784 | <li>HTML, a specific handler for the conversion of UTF-8 to ASCII with HTML
|
|---|
| 4785 | predefined entities like &copy; for the Copyright sign.</li>
|
|---|
| 4786 | </ol>
|
|---|
| 4787 |
|
|---|
| 4788 | <p>More over when compiled on an Unix platform with iconv support the full
|
|---|
| 4789 | set of encodings supported by iconv can be instantly be used by libxml. On a
|
|---|
| 4790 | linux machine with glibc-2.1 the list of supported encodings and aliases fill
|
|---|
| 4791 | 3 full pages, and include UCS-4, the full set of ISO-Latin encodings, and the
|
|---|
| 4792 | various Japanese ones.</p>
|
|---|
| 4793 |
|
|---|
| 4794 | <p>To convert from the UTF-8 values returned from the API to another encoding
|
|---|
| 4795 | then it is possible to use the function provided from <a
|
|---|
| 4796 | href="html/libxml-encoding.html">the encoding module</a> like <a
|
|---|
| 4797 | href="html/libxml-encoding.html#UTF8Toisolat1">UTF8Toisolat1</a>, or use the

|
|---|
| 4801 |
|
|---|
| 4802 | <h4>Encoding aliases</h4>
|
|---|
| 4803 |
|
|---|
| 4804 | <p>From 2.2.3, libxml2 has support to register encoding names aliases. The
|
|---|
| 4805 | goal is to be able to parse document whose encoding is supported but where
|
|---|
| 4806 | the name differs (for example from the default set of names accepted by
|
|---|
| 4807 | iconv). The following functions allow to register and handle new aliases for
|
|---|
| 4808 | existing encodings. Once registered libxml2 will automatically lookup the
|
|---|
| 4809 | aliases when handling a document:</p>
|
|---|
| 4810 | <ul>
|
|---|
| 4811 | <li>int xmlAddEncodingAlias(const char *name, const char *alias);</li>
|
|---|
| 4812 | <li>int xmlDelEncodingAlias(const char *alias);</li>
|
|---|
| 4813 | <li>const char * xmlGetEncodingAlias(const char *alias);</li>
|
|---|
| 4814 | <li>void xmlCleanupEncodingAliases(void);</li>
|
|---|
| 4815 | </ul>
|
|---|
| 4816 |
|
|---|
| 4817 | <h3><a name="extend">How to extend the existing support</a></h3>
|
|---|
| 4818 |
|
|---|
| 4819 | <p>Well adding support for new encoding, or overriding one of the encoders
|
|---|
| 4820 | (assuming it is buggy) should not be hard, just write input and output
|
|---|
| 4821 | conversion routines to/from UTF-8, and register them using
|
|---|
| 4822 | xmlNewCharEncodingHandler(name, xxxToUTF8, UTF8Toxxx), and they will be
|
|---|
| 4823 | called automatically if the parser(s) encounter such an encoding name
|
|---|
| 4824 | (register it uppercase, this will help). The description of the encoders,
|
|---|
| 4825 | their arguments and expected return values are described in the encoding.h
|
|---|
| 4826 | header.</p>

|
|---|
| 4848 | don't look at the public identifier since libxml2 do not maintain a

| 4862 | handlers for certain names.</p>
|
|---|
| 4863 | </li>
|
|---|
| 4864 | </ul>
|
|---|
| 4865 |
|
|---|
| 4866 | <p>The general mechanism used when loading http://rpmfind.net/xml.html for
|
|---|
| 4867 | example in the HTML parser is the following:</p>
|
|---|
| 4868 | <ol>
|
|---|
| 4869 | <li>The default entity loader calls <code>xmlNewInputFromFile()</code> with
|
|---|
| 4870 | the parsing context and the URI string.</li>
|
|---|
| 4871 | <li>the URI string is checked against the existing registered handlers
|
|---|
| 4872 | using their match() callback function, if the HTTP module was compiled
|
|---|
| 4873 | in, it is registered and its match() function will succeeds</li>
|
|---|
| 4874 | <li>the open() function of the handler is called and if successful will
|
|---|
| 4875 | return an I/O Input buffer</li>
|
|---|
| 4876 | <li>the parser will the start reading from this buffer and progressively
|
|---|
| 4877 | fetch information from the resource, calling the read() function of the
|
|---|
| 4878 | handler until the resource is exhausted</li>
|
|---|
| 4879 | <li>if an encoding change is detected it will be installed on the input
|
|---|
| 4880 | buffer, providing buffering and efficient use of the conversion
|
|---|
| 4881 | routines</li>
|
|---|
| 4882 | <li>once the parser has finished, the close() function of the handler is
|
|---|
| 4883 | called once and the Input buffer and associated resources are
|
|---|
| 4884 | deallocated.</li>
|
|---|
| 4885 | </ol>
|
|---|
| 4886 |
|
|---|
| 4887 | <p>The user defined callbacks are checked first to allow overriding of the
|
|---|
| 4888 | default libxml2 I/O routines.</p>

|---|
| 4890 | <h3><a name="basic">The basic buffer type</a></h3>
|
|---|
| 4891 |
|
|---|
| 4892 | <p>All the buffer manipulation handling is done using the
|
|---|
| 4893 | <code>xmlBuffer</code> type define in <code><a
|
|---|
| 4894 | href="http://xmlsoft.org/html/libxml-tree.html">tree.h</a> </code>which is a
|
|---|
| 4895 | resizable memory buffer. The buffer allocation strategy can be selected to be
|
|---|
| 4896 | either best-fit or use an exponential doubling one (CPU vs. memory use
|
|---|
| 4897 | trade-off). The values are <code>XML_BUFFER_ALLOC_EXACT</code> and
|
|---|
| 4898 | <code>XML_BUFFER_ALLOC_DOUBLEIT</code>, and can be set individually or on a
|
|---|
| 4899 | system wide basis using <code>xmlBufferSetAllocationScheme()</code>. A number
|
|---|
| 4900 | of functions allows to manipulate buffers with names starting with the
|
|---|
| 4901 | <code>xmlBuffer...</code> prefix.</p>
|
|---|
| 4902 |
|
|---|
| 4903 | <h3><a name="Input">Input I/O handlers</a></h3>
|
|---|
| 4904 |
|
|---|
| 4905 | <p>An Input I/O handler is a simple structure
|
|---|
| 4906 | <code>xmlParserInputBuffer</code> containing a context associated to the
|
|---|
| 4907 | resource (file descriptor, or pointer to a protocol handler), the read() and
|
|---|
| 4908 | close() callbacks to use and an xmlBuffer. And extra xmlBuffer and a charset
|
|---|
| 4909 | encoding handler are also present to support charset conversion when
|
|---|
| 4910 | needed.</p>
|
|---|
| 4911 |
|
|---|
| 4912 | <h3><a name="Output">Output I/O handlers</a></h3>
|
|---|
| 4913 |
|
|---|
| 4914 | <p>An Output handler <code>xmlOutputBuffer</code> is completely similar to an
|
|---|
| 4915 | Input one except the callbacks are write() and close().</p>
|
|---|
| 4916 |
|
|---|
| 4917 | <h3><a name="entities">The entities loader</a></h3>
|
|---|
| 4918 |
|
|---|
| 4919 | <p>The entity loader resolves requests for new entities and create inputs for
|
|---|
| 4920 | the parser. Creating an input from a filename or an URI string is done
|
|---|
| 4921 | through the xmlNewInputFromFile() routine. The default entity loader do not
|
|---|
| 4922 | handle the PUBLIC identifier associated with an entity (if any). So it just
|
|---|
| 4923 | calls xmlNewInputFromFile() with the SYSTEM identifier (which is mandatory in
|
|---|
| 4924 | XML).</p>
|
|---|
| 4925 |
|
|---|
| 4926 | <p>If you want to hook up a catalog mechanism then you simply need to
|
|---|
| 4927 | override the default entity loader, here is an example:</p>
|
|---|
| 4928 | <pre>#include <libxml/xmlIO.h>

|
|---|
| 4934 | xmlParserCtxtPtr ctxt) {
|
|---|
| 4935 | xmlParserInputPtr ret;
|
|---|
| 4936 | const char *fileID = NULL;
|
|---|
| 4937 | /* lookup for the fileID depending on ID */
|
|---|
| 4938 |
|

| 4942 | if (defaultLoader != NULL)
|
|---|
| 4943 | ret = defaultLoader(URL, ID, ctxt);
|
|---|
| 4944 | return(ret);
|
|---|
| 4945 | }
|
|---|
| 4946 |
|
|---|

|
|---|
| 5018 |
|
|---|
| 5019 | <p>What is a catalog? Basically it's a lookup mechanism used when an entity
|
|---|
| 5020 | (a file or a remote resource) references another entity. The catalog lookup
|
|---|
| 5021 | is inserted between the moment the reference is recognized by the software
|
|---|
| 5022 | (XML parser, stylesheet processing, or even images referenced for inclusion
|
|---|
| 5023 | in a rendering) and the time where loading that resource is actually
|
|---|
| 5024 | started.</p>
|
|---|
| 5025 |
|
|---|
| 5026 | <p>It is basically used for 3 things:</p>
|
|---|
| 5027 | <ul>
|
|---|
| 5028 | <li>mapping from "logical" names, the public identifiers and a more
|
|---|
| 5029 | concrete name usable for download (and URI). For example it can associate
|
|---|
| 5030 | the logical name
|
|---|
| 5031 | <p>"-//OASIS//DTD DocBook XML V4.1.2//EN"</p>
|
|---|
| 5032 | <p>of the DocBook 4.1.2 XML DTD with the actual URL where it can be
|
|---|
| 5033 | downloaded</p>
|
|---|
| 5034 | <p>http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd</p>
|
|---|
| 5035 | </li>
|
|---|
| 5036 | <li>remapping from a given URL to another one, like an HTTP indirection
|
|---|
| 5037 | saying that
|
|---|
| 5038 | <p>"http://www.oasis-open.org/committes/tr.xsl"</p>
|
|---|
| 5039 | <p>should really be looked at</p>
|
|---|
| 5040 | <p>"http://www.oasis-open.org/committes/entity/stylesheets/base/tr.xsl"</p>
|
|---|
| 5041 | </li>
|
|---|
| 5042 | <li>providing a local cache mechanism allowing to load the entities
|
|---|
| 5043 | associated to public identifiers or remote resources, this is a really
|
|---|
| 5044 | important feature for any significant deployment of XML or SGML since it
|
|---|
| 5045 | allows to avoid the aleas and delays associated to fetching remote
|
|---|
| 5046 | resources.</li>
|
|---|
| 5047 | </ul>
|
|---|
| 5048 |

|---|
| 5049 | <h3><a name="definition">The definitions</a></h3>
|
|---|
| 5050 |
|
|---|
| 5051 | <p>Libxml, as of 2.4.3 implements 2 kind of catalogs:</p>
|
|---|
| 5052 | <ul>
|
|---|
| 5053 | <li>the older SGML catalogs, the official spec is SGML Open Technical
|
|---|
| 5054 | Resolution TR9401:1997, but is better understood by reading <a
|
|---|
| 5055 | href="http://www.jclark.com/sp/catalog.htm">the SP Catalog page</a> from
|
|---|
| 5056 | James Clark. This is relatively old and not the preferred mode of
|
|---|
| 5057 | operation of libxml.</li>
|
|---|
| 5058 | <li><a href="http://www.oasis-open.org/committees/entity/spec.html">XML
|
|---|
| 5059 | Catalogs</a> is far more flexible, more recent, uses an XML syntax and
|
|---|
| 5060 | should scale quite better. This is the default option of libxml.</li>
|
|---|
| 5061 | </ul>
|
|---|
| 5062 |
|
|---|
| 5063 | <p></p>
|

| 5064 |
|
|---|
| 5065 | <h3><a name="Simple">Using catalog</a></h3>
|
|---|
| 5066 |
|
|---|
| 5067 | <p>In a normal environment libxml2 will by default check the presence of a
|
|---|
| 5068 | catalog in /etc/xml/catalog, and assuming it has been correctly populated,
|
|---|
| 5069 | the processing is completely transparent to the document user. To take a
|
|---|
| 5070 | concrete example, suppose you are authoring a DocBook document, this one
|
|---|
| 5071 | starts with the following DOCTYPE definition:</p>
|
|---|
| 5072 | <pre><?xml version='1.0'?>
|
|---|
| 5073 | <!DOCTYPE book PUBLIC "-//Norman Walsh//DTD DocBk XML V3.1.4//EN"
|
|---|
| 5074 | "http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd"></pre>
|
|---|
| 5075 |
|
|---|
| 5076 | <p>When validating the document with libxml, the catalog will be
|
|---|
| 5077 | automatically consulted to lookup the public identifier "-//Norman Walsh//DTD
|
|---|
| 5078 | DocBk XML V3.1.4//EN" and the system identifier
|
|---|
| 5079 | "http://nwalsh.com/docbook/xml/3.1.4/db3xml.dtd", and if these entities have
|
|---|
| 5080 | been installed on your system and the catalogs actually point to them, libxml
|
|---|
| 5081 | will fetch them from the local disk.</p>
|
|---|
| 5082 |
|
|---|
| 5083 | <p style="font-size: 10pt"><strong>Note</strong>: Really don't use this
|
|---|
| 5084 | DOCTYPE example it's a really old version, but is fine as an example.</p>
|
|---|
| 5085 |
|
|---|
| 5086 | <p>Libxml2 will check the catalog each time that it is requested to load an
|
|---|
| 5087 | entity, this includes DTD, external parsed entities, stylesheets, etc ... If
|
|---|
| 5088 | your system is correctly configured all the authoring phase and processing
|
|---|
| 5089 | should use only local files, even if your document stays portable because it
|
|---|
| 5090 | uses the canonical public and system ID, referencing the remote document.</p>

|

| 5093 |
|

|
|---|
| 5106 | written in XML, there is a specific namespace for catalog elements
|
|---|
| 5107 | "urn:oasis:names:tc:entity:xmlns:xml:catalog". The first entry in this
|
|---|
| 5108 | catalog is a <code>public</code> mapping it allows to associate a Public

|
|---|
| 5114 |
|
|---|
| 5115 | <p>A <code>rewriteSystem</code> is a very powerful instruction, it says that
|
|---|
| 5116 | any URI starting with a given prefix should be looked at another URI
|
|---|
| 5117 | constructed by replacing the prefix with an new one. In effect this acts like
|
|---|
| 5118 | a cache system for a full area of the Web. In practice it is extremely useful
|
|---|
| 5119 | with a file prefix if you have installed a copy of those resources on your

| 5137 | entries in another resource. This feature allow to build hierarchies of
|
|---|
| 5138 | catalogs, the set of entries presented should be sufficient to redirect the
|
|---|
| 5139 | resolution of all DocBook references to the specific catalog in
|
|---|
| 5140 | <code>/usr/share/xml/docbook.xml</code> this one in turn could delegate all

|

| 5146 | <p>The user can change the default catalog behaviour by redirecting queries
|
|---|
| 5147 | to its own set of catalogs, this can be done by setting the
|
|---|
| 5148 | <code>XML_CATALOG_FILES</code> environment variable to a list of catalogs, an
|
|---|
| 5149 | empty one should deactivate loading the default <code>/etc/xml/catalog</code>

|

| 5172 |
|

| 5173 | <p>But the most advanced way to debug XML catalog processing is to use the

| 5216 | <h3><a name="Declaring">How to create and maintain</a> catalogs:</h3>
|
|---|
| 5217 |
|
|---|
| 5218 | <p>Basically XML Catalogs are XML files, you can either use XML tools to
|
|---|
| 5219 | manage them or use <strong>xmlcatalog</strong> for this. The basic step is
|
|---|
| 5220 | to create a catalog the -create option provide this facility:</p>
|
|---|
| 5221 | <pre>orchis:~/XML -> ./xmlcatalog --create tst.xml
|
|---|
| 5222 | <?xml version="1.0"?>
|
|---|
| 5223 | <!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN"
|
|---|
| 5224 | "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd">
|
|---|
| 5225 | <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"/>
|
|---|
| 5226 | orchis:~/XML -> </pre>
|
|---|
| 5227 |
|
|---|
| 5228 | <p>By default xmlcatalog does not overwrite the original catalog and save the
|
|---|
| 5229 | result on the standard output, this can be overridden using the -noout
|
|---|
| 5230 | option. The <code>-add</code> command allows to add entries in the
|
|---|
| 5231 | catalog:</p>
|
|---|
| 5232 | <pre>orchis:~/XML -> ./xmlcatalog --noout --create --add "public" \
|
|---|
| 5233 | "-//OASIS//DTD DocBook XML V4.1.2//EN" \
|
|---|
| 5234 | http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd tst.xml
|
|---|
| 5235 | orchis:~/XML -> cat tst.xml
|
|---|
| 5236 | <?xml version="1.0"?>
|
|---|
| 5237 | <!DOCTYPE catalog PUBLIC "-//OASIS//DTD Entity Resolution XML Catalog V1.0//EN" \
|
|---|
| 5238 | "http://www.oasis-open.org/committees/entity/release/1.0/catalog.dtd">

|---|
| 5239 | <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog">

|
|---|
| 5243 | orchis:~/XML -> </pre>
|
|---|
| 5244 |
|
|---|
| 5245 | <p>The <code>-add</code> option will always take 3 parameters even if some of
|
|---|
| 5246 | the XML Catalog constructs (like nextCatalog) will have only a single
|
|---|
| 5247 | argument, just pass a third empty string, it will be ignored.</p>
|
|---|
| 5248 |
|
|---|
| 5249 | <p>Similarly the <code>-del</code> option remove matching entries from the
|
|---|
| 5250 | catalog:</p>
|
|---|
| 5251 | <pre>orchis:~/XML -> ./xmlcatalog --del \
|
|---|
| 5252 | "http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd" tst.xml
|
|---|
| 5253 | <?xml version="1.0"?>

|
|---|

|---|
| 5256 | <catalog xmlns="urn:oasis:names:tc:entity:xmlns:xml:catalog"/>
|
|---|
| 5257 | orchis:~/XML -> </pre>
|
|---|
| 5258 |
|
|---|
| 5259 | <p>The catalog is now empty. Note that the matching of <code>-del</code> is
|
|---|
| 5260 | exact and would have worked in a similar fashion with the Public ID
|
|---|
| 5261 | string.</p>
|
|---|
| 5262 |
|
|---|
| 5263 | <p>This is rudimentary but should be sufficient to manage a not too complex
|
|---|
| 5264 | catalog tree of resources.</p>
|

|
|---|
| 5266 | <h3><a name="implemento">The implementor corner quick review of the
|
|---|
| 5267 | API:</a></h3>
|
|---|
| 5268 |
|
|---|
| 5269 | <p>First, and like for every other module of libxml, there is an
|
|---|
| 5270 | automatically generated <a href="html/libxml-catalog.html">API page for
|
|---|
| 5271 | catalog support</a>.</p>
|
|---|
| 5272 |
|
|---|
| 5273 | <p>The header for the catalog interfaces should be included as:</p>
|
|---|
| 5274 | <pre>#include <libxml/catalog.h></pre>
|
|---|
| 5275 |
|
|---|
| 5276 | <p>The API is voluntarily kept very simple. First it is not obvious that
|
|---|
| 5277 | applications really need access to it since it is the default behaviour of
|
|---|
| 5278 | libxml2 (Note: it is possible to completely override libxml2 default catalog
|
|---|
| 5279 | by using <a href="html/libxml-parser.html">xmlSetExternalEntityLoader</a> to
|
|---|
| 5280 | plug an application specific resolver).</p>
|
|---|
| 5281 |
|
|---|
| 5282 | <p>Basically libxml2 support 2 catalog lists:</p>
|
|---|
| 5283 | <ul>
|
|---|
| 5284 | <li>the default one, global shared by all the application</li>
|
|---|
| 5285 | <li>a per-document catalog, this one is built if the document uses the
|
|---|
| 5286 | <code>oasis-xml-catalog</code> PIs to specify its own catalog list, it is
|
|---|
| 5287 | associated to the parser context and destroyed when the parsing context
|
|---|
| 5288 | is destroyed.</li>
|
|---|
| 5289 | </ul>
|
|---|
| 5290 |
|
|---|
| 5291 | <p>the document one will be used first if it exists.</p>
|
|---|
| 5292 |
|
|---|
| 5293 | <h4>Initialization routines:</h4>
|
|---|
| 5294 |
|
|---|
| 5295 | <p>xmlInitializeCatalog(), xmlLoadCatalog() and xmlLoadCatalogs() should be
|
|---|
| 5296 | used at startup to initialize the catalog, if the catalog should be
|
|---|
| 5297 | initialized with specific values xmlLoadCatalog() or xmlLoadCatalogs()
|
|---|
| 5298 | should be called before xmlInitializeCatalog() which would otherwise do a
|
|---|
| 5299 | default initialization first.</p>
|
|---|
| 5300 |
|
|---|
| 5301 | <p>The xmlCatalogAddLocal() call is used by the parser to grow the document
|
|---|
| 5302 | own catalog list if needed.</p>
|
|---|
| 5303 |
|
|---|
| 5304 | <h4>Preferences setup:</h4>
|
|---|
| 5305 |
|
|---|
| 5306 | <p>The XML Catalog spec requires the possibility to select default
|
|---|
| 5307 | preferences between public and system delegation,
|
|---|
| 5308 | xmlCatalogSetDefaultPrefer() allows this, xmlCatalogSetDefaults() and
|
|---|
| 5309 | xmlCatalogGetDefaults() allow to control if XML Catalogs resolution should
|
|---|
| 5310 | be forbidden, allowed for global catalog, for document catalog or both, the
|
|---|
| 5311 | default is to allow both.</p>
|
|---|
| 5312 |
|
|---|
| 5313 | <p>And of course xmlCatalogSetDebug() allows to generate debug messages
|
|---|
| 5314 | (through the xmlGenericError() mechanism).</p>
|
|---|
| 5315 |
|
|---|
| 5316 | <h4>Querying routines:</h4>
|
|---|
| 5317 |
|
|---|
| 5318 | <p>xmlCatalogResolve(), xmlCatalogResolveSystem(), xmlCatalogResolvePublic()
|
|---|
| 5319 | and xmlCatalogResolveURI() are relatively explicit if you read the XML
|
|---|
| 5320 | Catalog specification they correspond to section 7 algorithms, they should
|
|---|
| 5321 | also work if you have loaded an SGML catalog with a simplified semantic.</p>
|
|---|
| 5322 |
|
|---|
| 5323 | <p>xmlCatalogLocalResolve() and xmlCatalogLocalResolveURI() are the same but
|
|---|
| 5324 | operate on the document catalog list</p>
|
|---|
| 5325 |
|
|---|
| 5326 | <h4>Cleanup and Miscellaneous:</h4>
|
|---|
| 5327 |
|
|---|
| 5328 | <p>xmlCatalogCleanup() free-up the global catalog, xmlCatalogFreeLocal() is
|
|---|
| 5329 | the per-document equivalent.</p>
|
|---|
| 5330 |
|
|---|
| 5331 | <p>xmlCatalogAdd() and xmlCatalogRemove() are used to dynamically modify the
|
|---|
| 5332 | first catalog in the global list, and xmlCatalogDump() allows to dump a
|
|---|
| 5333 | catalog state, those routines are primarily designed for xmlcatalog, I'm not
|
|---|
| 5334 | sure that exposing more complex interfaces (like navigation ones) would be
|
|---|
| 5335 | really useful.</p>
|
|---|
| 5336 |
|
|---|
| 5337 | <p>The xmlParseCatalogFile() is a function used to load XML Catalog files,
|
|---|
| 5338 | it's similar as xmlParseFile() except it bypass all catalog lookups, it's
|
|---|
| 5339 | provided because this functionality may be useful for client tools.</p>
|
|---|
| 5340 |
|
|---|
| 5341 | <h4>threaded environments:</h4>
|
|---|
| 5342 |
|
|---|
| 5343 | <p>Since the catalog tree is built progressively, some care has been taken to
|
|---|
| 5344 | try to avoid troubles in multithreaded environments. The code is now thread
|
|---|
| 5345 | safe assuming that the libxml2 library has been compiled with threads
|
|---|
| 5346 | support.</p>

|---|

|
|---|
| 5392 |
|
|---|
| 5393 | <p>This section is directly intended to help programmers getting bootstrapped
|
|---|
| 5394 | using the XML tollkit from the C language. It is not intended to be
|
|---|
| 5395 | extensive. I hope the automatically generated documents will provide the
|
|---|
| 5396 | completeness required, but as a separate set of documents. The interfaces of
|
|---|
| 5397 | the XML parser are by principle low level, Those interested in a higher level
|
|---|
| 5398 | API should <a href="#DOM">look at DOM</a>.</p>
|
|---|
| 5399 |
|
|---|
| 5400 | <p>The <a href="html/libxml-parser.html">parser interfaces for XML</a> are
|
|---|
| 5401 | separated from the <a href="html/libxml-htmlparser.html">HTML parser
|
|---|
| 5402 | interfaces</a>. Let's have a look at how the XML parser can be called:</p>

| 5403 |
|
|---|
| 5404 | <h3><a name="Invoking">Invoking the parser : the pull method</a></h3>
|
|---|
| 5405 |
|
|---|
| 5406 | <p>Usually, the first thing to do is to read an XML input. The parser accepts
|
|---|
| 5407 | documents either from in-memory strings or from files. The functions are
|
|---|
| 5408 | defined in "parser.h":</p>
|
|---|
| 5409 | <dl>
|
|---|
| 5410 | <dt><code>xmlDocPtr xmlParseMemory(char *buffer, int size);</code></dt>
|
|---|
| 5411 | <dd><p>Parse a null-terminated string containing the document.</p>
|
|---|
| 5412 | </dd>
|
|---|
| 5413 | </dl>
|
|---|
| 5414 | <dl>
|
|---|
| 5415 | <dt><code>xmlDocPtr xmlParseFile(const char *filename);</code></dt>
|
|---|
| 5416 | <dd><p>Parse an XML document contained in a (possibly compressed)
|
|---|
| 5417 | file.</p>
|
|---|
| 5418 | </dd>
|
|---|
| 5419 | </dl>
|
|---|
| 5420 |
|
|---|
| 5421 | <p>The parser returns a pointer to the document structure (or NULL in case of
|
|---|
| 5422 | failure).</p>
|
|---|
| 5423 |
|
|---|
| 5424 | <h3 id="Invoking1">Invoking the parser: the push method</h3>
|
|---|
| 5425 |
|
|---|
| 5426 | <p>In order for the application to keep the control when the document is
|
|---|
| 5427 | being fetched (which is common for GUI based programs) libxml2 provides a
|
|---|
| 5428 | push interface, too, as of version 1.8.3. Here are the interface
|
|---|
| 5429 | functions:</p>
|
|---|
| 5430 | <pre>xmlParserCtxtPtr xmlCreatePushParserCtxt(xmlSAXHandlerPtr sax,
|
|---|
| 5431 | void *user_data,
|
|---|
| 5432 | const char *chunk,
|
|---|
| 5433 | int size,
|
|---|
| 5434 | const char *filename);
|
|---|
| 5435 | int xmlParseChunk (xmlParserCtxtPtr ctxt,
|
|---|
| 5436 | const char *chunk,
|
|---|
| 5437 | int size,
|
|---|
| 5438 | int terminate);</pre>
|
|---|
| 5439 |
|
|---|
| 5440 | <p>and here is a simple example showing how to use the interface:</p>
|
|---|
| 5441 | <pre> FILE *f;
|
|---|
| 5442 |
|
|---|
| 5443 | f = fopen(filename, "r");
|
|---|
| 5444 | if (f != NULL) {
|
|---|
| 5445 | int res, size = 1024;
|
|---|
| 5446 | char chars[1024];
|
|---|
| 5447 | xmlParserCtxtPtr ctxt;
|
|---|
| 5448 |
|
|---|
| 5449 | res = fread(chars, 1, 4, f);
|
|---|
| 5450 | if (res > 0) {
|
|---|
| 5451 | ctxt = xmlCreatePushParserCtxt(NULL, NULL,
|
|---|
| 5452 | chars, res, filename);
|
|---|
| 5453 | while ((res = fread(chars, 1, size, f)) > 0) {
|
|---|
| 5454 | xmlParseChunk(ctxt, chars, res, 0);
|
|---|
| 5455 | }
|
|---|
| 5456 | xmlParseChunk(ctxt, chars, 0, 1);
|
|---|
| 5457 | doc = ctxt->myDoc;
|
|---|
| 5458 | xmlFreeParserCtxt(ctxt);
|
|---|
| 5459 | }
|
|---|
| 5460 | }</pre>
|
|---|
| 5461 |
|
|---|
| 5462 | <p>The HTML parser embedded into libxml2 also has a push interface; the
|
|---|
| 5463 | functions are just prefixed by "html" rather than "xml".</p>
|
|---|
| 5464 |
|
|---|
| 5465 | <h3 id="Invoking2">Invoking the parser: the SAX interface</h3>
|
|---|
| 5466 |
|
|---|
| 5467 | <p>The tree-building interface makes the parser memory-hungry, first loading
|
|---|
| 5468 | the document in memory and then building the tree itself. Reading a document
|

|
|---|
| 5476 |
|
|---|
| 5477 | <p>The other way to get an XML tree in memory is by building it. Basically
|
|---|
| 5478 | there is a set of functions dedicated to building new elements. (These are
|
|---|
| 5479 | also described in <libxml/tree.h>.) For example, here is a piece of
|
|---|
| 5480 | code that produces the XML document used in the previous examples:</p>
|
|---|
| 5481 | <pre> #include <libxml/tree.h>
|
|---|
| 5482 | xmlDocPtr doc;
|
|---|
| 5483 | xmlNodePtr tree, subtree;
|
|---|
| 5484 |
|
|---|
| 5485 | doc = xmlNewDoc("1.0");
|
|---|
| 5486 | doc->children = xmlNewDocNode(doc, NULL, "EXAMPLE", NULL);
|
|---|
| 5487 | xmlSetProp(doc->children, "prop1", "gnome is great");
|
|---|
| 5488 | xmlSetProp(doc->children, "prop2", "& linux too");
|
|---|
| 5489 | tree = xmlNewChild(doc->children, NULL, "head", NULL);
|
|---|
| 5490 | subtree = xmlNewChild(tree, NULL, "title", "Welcome to Gnome");
|
|---|
| 5491 | tree = xmlNewChild(doc->children, NULL, "chapter", NULL);
|
|---|
| 5492 | subtree = xmlNewChild(tree, NULL, "title", "The Linux adventure");
|
|---|
| 5493 | subtree = xmlNewChild(tree, NULL, "p", "bla bla bla ...");
|
|---|
| 5494 | subtree = xmlNewChild(tree, NULL, "image", NULL);
|
|---|
| 5495 | xmlSetProp(subtree, "href", "linus.gif");</pre>
|
|---|
| 5496 |
|
|---|
| 5497 | <p>Not really rocket science ...</p>

| 5499 | <h3><a name="Traversing">Traversing the tree</a></h3>
|
|---|
| 5500 |
|
|---|
| 5501 | <p>Basically by <a href="html/libxml-tree.html">including "tree.h"</a> your
|
|---|
| 5502 | code has access to the internal structure of all the elements of the tree.
|
|---|
| 5503 | The names should be somewhat simple like <strong>parent</strong>,
|
|---|
| 5504 | <strong>children</strong>, <strong>next</strong>, <strong>prev</strong>,
|
|---|
| 5505 | <strong>properties</strong>, etc... For example, still with the previous
|
|---|
| 5506 | example:</p>
|
|---|
| 5507 | <pre><code>doc->children->children->children</code></pre>
|
|---|
| 5508 |
|
|---|
| 5509 | <p>points to the title element,</p>
|
|---|
| 5510 | <pre>doc->children->children->next->children->children</pre>
|
|---|
| 5511 |
|
|---|
| 5512 | <p>points to the text node containing the chapter title "The Linux
|
|---|
| 5513 | adventure".</p>
|
|---|
| 5514 |
|
|---|
| 5515 | <p><strong>NOTE</strong>: XML allows <em>PI</em>s and <em>comments</em> to be
|
|---|
| 5516 | present before the document root, so <code>doc->children</code> may point
|
|---|
| 5517 | to an element which is not the document Root Element; a function
|
|---|
| 5518 | <code>xmlDocGetRootElement()</code> was added for this purpose.</p>

| 5611 | <h2><a name="Entities">Entities or no entities</a></h2>
|
|---|
| 5612 |
|
|---|
| 5613 | <p>Entities in principle are similar to simple C macros. An entity defines an
|
|---|
| 5614 | abbreviation for a given string that you can reuse many times throughout the
|
|---|
| 5615 | content of your document. Entities are especially useful when a given string
|
|---|
| 5616 | may occur frequently within a document, or to confine the change needed to a
|
|---|
| 5617 | document to a restricted area in the internal subset of the document (at the
|
|---|
| 5618 | beginning). Example:</p>
|
|---|
| 5619 | <pre>1 <?xml version="1.0"?>
|
|---|
| 5620 | 2 <!DOCTYPE EXAMPLE SYSTEM "example.dtd" [
|
|---|
| 5621 | 3 <!ENTITY xml "Extensible Markup Language">
|
|---|
| 5622 | 4 ]>
|
|---|
| 5623 | 5 <EXAMPLE>
|
|---|
| 5624 | 6 &xml;
|
|---|
| 5625 | 7 </EXAMPLE></pre>
|
|---|
| 5626 |
|
|---|
| 5627 | <p>Line 3 declares the xml entity. Line 6 uses the xml entity, by prefixing
|
|---|
| 5628 | its name with '&' and following it by ';' without any spaces added. There
|
|---|
| 5629 | are 5 predefined entities in libxml2 allowing you to escape characters with
|
|---|
| 5630 | predefined meaning in some parts of the xml document content:
|
|---|
| 5631 | <strong>&lt;</strong> for the character '<', <strong>&gt;</strong>
|
|---|
| 5632 | for the character '>', <strong>&apos;</strong> for the character ''',
|
|---|
| 5633 | <strong>&quot;</strong> for the character '"', and
|
|---|
| 5634 | <strong>&amp;</strong> for the character '&'.</p>
|
|---|
| 5635 |
|
|---|
| 5636 | <p>One of the problems related to entities is that you may want the parser to
|
|---|
| 5637 | substitute an entity's content so that you can see the replacement text in
|
|---|
| 5638 | your application. Or you may prefer to keep entity references as such in the
|
|---|
| 5639 | content to be able to save the document back without losing this usually
|
|---|
| 5640 | precious information (if the user went through the pain of explicitly
|
|---|
| 5641 | defining entities, he may have a a rather negative attitude if you blindly
|
|---|
| 5642 | substitute them as saving time). The <a
|
|---|
| 5643 | href="html/libxml-parser.html#xmlSubstituteEntitiesDefault">xmlSubstituteEntitiesDefault()</a>
|
|---|
| 5644 | function allows you to check and change the behaviour, which is to not
|
|---|
| 5645 | substitute entities by default.</p>
|
|---|
| 5646 |
|
|---|
| 5647 | <p>Here is the DOM tree built by libxml2 for the previous document in the
|
|---|
| 5648 | default case:</p>
|
|---|
| 5649 | <pre>/gnome/src/gnome-xml -> ./xmllint --debug test/ent1
|
|---|
| 5650 | DOCUMENT
|
|---|
| 5651 | version=1.0
|
|---|
| 5652 | ELEMENT EXAMPLE
|
|---|
| 5653 | TEXT
|
|---|
| 5654 | content=
|
|---|
| 5655 | ENTITY_REF
|
|---|
| 5656 | INTERNAL_GENERAL_ENTITY xml
|
|---|
| 5657 | content=Extensible Markup Language

| 5658 | TEXT
|
|---|
| 5659 | content=</pre>
|
|---|
| 5660 |
|
|---|
| 5661 | <p>And here is the result when substituting entities:</p>
|
|---|
| 5662 | <pre>/gnome/src/gnome-xml -> ./tester --debug --noent test/ent1
|
|---|
| 5663 | DOCUMENT
|
|---|

|
|---|
| 5666 | TEXT
|
|---|
| 5667 | content= Extensible Markup Language</pre>
|
|---|
| 5668 |
|
|---|
| 5669 | <p>So, entities or no entities? Basically, it depends on your use case. I
|
|---|
| 5670 | suggest that you keep the non-substituting default behaviour and avoid using
|
|---|
| 5671 | entities in your XML document or data if you are not willing to handle the
|
|---|
| 5672 | entity references elements in the DOM tree.</p>
|
|---|
| 5673 |
|
|---|
| 5674 | <p>Note that at save time libxml2 enforces the conversion of the predefined
|
|---|
| 5675 | entities where necessary to prevent well-formedness problems, and will also
|
|---|
| 5676 | transparently replace those with chars (i.e. it will not generate entity
|
|---|
| 5677 | reference elements in the DOM tree or call the reference() SAX callback when
|
|---|
| 5678 | finding them in the input).</p>
|
|---|
| 5679 |
|
|---|
| 5680 | <p><span style="background-color: #FF0000">WARNING</span>: handling entities
|
|---|
| 5681 | on top of the libxml2 SAX interface is difficult!!! If you plan to use
|
|---|
| 5682 | non-predefined entities in your documents, then the learning curve to handle
|
|---|
| 5683 | then using the SAX API may be long. If you plan to use complex documents, I
|
|---|
| 5684 | strongly suggest you consider using the DOM interface instead and let libxml
|
|---|
| 5685 | deal with the complexity rather than trying to do it yourself.</p>

| 5687 | <h2><a name="Namespaces">Namespaces</a></h2>
|
|---|
| 5688 |
|
|---|
| 5689 | <p>The libxml2 library implements <a
|
|---|
| 5690 | href="http://www.w3.org/TR/REC-xml-names/">XML namespaces</a> support by
|
|---|
| 5691 | recognizing namespace constructs in the input, and does namespace lookup
|
|---|
| 5692 | automatically when building the DOM tree. A namespace declaration is
|
|---|
| 5693 | associated with an in-memory structure and all elements or attributes within
|
|---|
| 5694 | that namespace point to it. Hence testing the namespace is a simple and fast
|
|---|
| 5695 | equality operation at the user level.</p>
|
|---|
| 5696 |
|
|---|
| 5697 | <p>I suggest that people using libxml2 use a namespace, and declare it in the
|
|---|
| 5698 | root element of their document as the default namespace. Then they don't need
|
|---|
| 5699 | to use the prefix in the content but we will have a basis for future semantic
|
|---|
| 5700 | refinement and merging of data from different sources. This doesn't increase
|
|---|
| 5701 | the size of the XML output significantly, but significantly increases its
|
|---|
| 5702 | value in the long-term. Example:</p>
|
|---|
| 5703 | <pre><mydoc xmlns="http://mydoc.example.org/schemas/">
|
|---|
| 5704 | <elem1>...</elem1>
|
|---|
| 5705 | <elem2>...</elem2>
|
|---|
| 5706 | </mydoc></pre>
|
|---|
| 5707 |
|
|---|
| 5708 | <p>The namespace value has to be an absolute URL, but the URL doesn't have to
|
|---|
| 5709 | point to any existing resource on the Web. It will bind all the element and
|
|---|
| 5710 | attributes with that URL. I suggest to use an URL within a domain you
|
|---|
| 5711 | control, and that the URL should contain some kind of version information if
|
|---|
| 5712 | possible. For example, <code>"http://www.gnome.org/gnumeric/1.0/"</code> is a
|
|---|
| 5713 | good namespace scheme.</p>
|
|---|
| 5714 |
|
|---|
| 5715 | <p>Then when you load a file, make sure that a namespace carrying the
|
|---|
| 5716 | version-independent prefix is installed on the root element of your document,
|
|---|
| 5717 | and if the version information don't match something you know, warn the user
|
|---|
| 5718 | and be liberal in what you accept as the input. Also do *not* try to base
|
|---|
| 5719 | namespace checking on the prefix value. <foo:text> may be exactly the
|
|---|
| 5720 | same as <bar:text> in another document. What really matters is the URI
|
|---|
| 5721 | associated with the element or the attribute, not the prefix string (which is
|
|---|
| 5722 | just a shortcut for the full URI). In libxml, element and attributes have an
|
|---|
| 5723 | <code>ns</code> field pointing to an xmlNs structure detailing the namespace
|
|---|
| 5724 | prefix and its URI.</p>

|

|
|---|
| 5735 | I will try to make sure that using namespaces won't break validity checking,
|
|---|
| 5736 | so even if you plan to use or currently are using validation I strongly
|
|---|
| 5737 | suggest adding namespaces to your document. A default namespace scheme
|
|---|
| 5738 | <code>xmlns="http://...."</code> should not break validity even on less
|
|---|
| 5739 | flexible parsers. Using namespaces to mix and differentiate content coming
|
|---|
| 5740 | from multiple DTDs will certainly break current validation schemes. To check
|
|---|
| 5741 | such documents one needs to use schema-validation, which is supported in
|
|---|
| 5742 | libxml2 as well. See <a href="http://www.relaxng.org/">relagx-ng</a> and <a

| 5774 | <li>The package name have changed from libxml to libxml2, the library name
|
|---|
| 5775 | is now -lxml2 . There is a new xml2-config script which should be used to
|
|---|
| 5776 | select the right parameters libxml2</li>
|
|---|
| 5777 | <li>Node <strong>childs</strong> field has been renamed
|
|---|
| 5778 | <strong>children</strong> so s/childs/children/g should be applied
|
|---|
| 5779 | (probability of having "childs" anywhere else is close to 0+</li>
|
|---|
| 5780 | <li>The document don't have anymore a <strong>root</strong> element it has
|
|---|
| 5781 | been replaced by <strong>children</strong> and usually you will get a
|
|---|
| 5782 | list of element here. For example a Dtd element for the internal subset
|
|---|
| 5783 | and it's declaration may be found in that list, as well as processing
|
|---|
| 5784 | instructions or comments found before or after the document root element.
|
|---|
| 5785 | Use <strong>xmlDocGetRootElement(doc)</strong> to get the root element of
|
|---|
| 5786 | a document. Alternatively if you are sure to not reference DTDs nor have
|
|---|
| 5787 | PIs or comments before or after the root element
|
|---|
| 5788 | s/->root/->children/g will probably do it.</li>
|
|---|
| 5789 | <li>The white space issue, this one is more complex, unless special case of
|
|---|
| 5790 | validating parsing, the line breaks and spaces usually used for indenting
|
|---|
| 5791 | and formatting the document content becomes significant. So they are
|
|---|
| 5792 | reported by SAX and if your using the DOM tree, corresponding nodes are
|
|---|
| 5793 | generated. Too approach can be taken:
|
|---|
| 5794 | <ol>
|
|---|
| 5795 | <li>lazy one, use the compatibility call
|
|---|
| 5796 | <strong>xmlKeepBlanksDefault(0)</strong> but be aware that you are
|
|---|
| 5797 | relying on a special (and possibly broken) set of heuristics of
|
|---|
| 5798 | libxml to detect ignorable blanks. Don't complain if it breaks or
|
|---|
| 5799 | make your application not 100% clean w.r.t. to it's input.</li>
|
|---|
| 5800 | <li>the Right Way: change you code to accept possibly insignificant
|
|---|
| 5801 | blanks characters, or have your tree populated with weird blank text
|
|---|
| 5802 | nodes. You can spot them using the commodity function
|
|---|
| 5803 | <strong>xmlIsBlankNode(node)</strong> returning 1 for such blank
|
|---|
| 5804 | nodes.</li>
|
|---|
| 5805 | </ol>
|
|---|
| 5806 | <p>Note also that with the new default the output functions don't add any
|
|---|
| 5807 | extra indentation when saving a tree in order to be able to round trip
|
|---|
| 5808 | (read and save) without inflating the document with extra formatting
|
|---|
| 5809 | chars.</p>
|
|---|
| 5810 | </li>
|
|---|
| 5811 | <li>The include path has changed to $prefix/libxml/ and the includes
|
|---|
| 5812 | themselves uses this new prefix in includes instructions... If you are
|
|---|
| 5813 | using (as expected) the
|
|---|
| 5814 | <pre>xml2-config --cflags</pre>
|
|---|
| 5815 | <p>output to generate you compile commands this will probably work out of
|
|---|
| 5816 | the box</p>
|
|---|
| 5817 | </li>
|
|---|
| 5818 | <li>xmlDetectCharEncoding takes an extra argument indicating the length in
|
|---|
| 5819 | byte of the head of the document available for character detection.</li>
|
|---|
| 5820 | </ol>
|
|---|
| 5821 |
|
|---|
| 5822 | <h3>Ensuring both libxml-1.x and libxml-2.x compatibility</h3>
|
|---|
| 5823 |
|
|---|
| 5824 | <p>Two new version of libxml (1.8.11) and libxml2 (2.3.4) have been released
|
|---|
| 5825 | to allow smooth upgrade of existing libxml v1code while retaining
|
|---|
| 5826 | compatibility. They offers the following:</p>
|
|---|
| 5827 | <ol>
|
|---|
| 5828 | <li>similar include naming, one should use
|
|---|
| 5829 | <strong>#include<libxml/...></strong> in both cases.</li>
|
|---|
| 5830 | <li>similar identifiers defined via macros for the child and root fields:
|
|---|
| 5831 | respectively <strong>xmlChildrenNode</strong> and
|
|---|
| 5832 | <strong>xmlRootNode</strong></li>
|
|---|
| 5833 | <li>a new macro <strong>LIBXML_TEST_VERSION</strong> which should be
|
|---|
| 5834 | inserted once in the client code</li>
|
|---|
| 5835 | </ol>
|
|---|
| 5836 |
|
|---|
| 5837 | <p>So the roadmap to upgrade your existing libxml applications is the
|
|---|
| 5838 | following:</p>
|
|---|
| 5839 | <ol>
|
|---|
| 5840 | <li>install the libxml-1.8.8 (and libxml-devel-1.8.8) packages</li>
|
|---|
| 5841 | <li>find all occurrences where the xmlDoc <strong>root</strong> field is
|
|---|
| 5842 | used and change it to <strong>xmlRootNode</strong></li>
|
|---|
| 5843 | <li>similarly find all occurrences where the xmlNode
|
|---|
| 5844 | <strong>childs</strong> field is used and change it to
|
|---|
| 5845 | <strong>xmlChildrenNode</strong></li>
|
|---|
| 5846 | <li>add a <strong>LIBXML_TEST_VERSION</strong> macro somewhere in your
|
|---|
| 5847 | <strong>main()</strong> or in the library init entry point</li>
|
|---|
| 5848 | <li>Recompile, check compatibility, it should still work</li>
|
|---|
| 5849 | <li>Change your configure script to look first for xml2-config and fall
|
|---|
| 5850 | back using xml-config . Use the --cflags and --libs output of the command
|
|---|
| 5851 | as the Include and Linking parameters needed to use libxml.</li>
|
|---|
| 5852 | <li>install libxml2-2.3.x and libxml2-devel-2.3.x (libxml-1.8.y and
|
|---|
| 5853 | libxml-devel-1.8.y can be kept simultaneously)</li>
|
|---|
| 5854 | <li>remove your config.cache, relaunch your configuration mechanism, and
|
|---|
| 5855 | recompile, if steps 2 and 3 were done right it should compile as-is</li>
|
|---|
| 5856 | <li>Test that your application is still running correctly, if not this may
|
|---|
| 5857 | be due to extra empty nodes due to formating spaces being kept in libxml2
|
|---|
| 5858 | contrary to libxml1, in that case insert xmlKeepBlanksDefault(1) in your
|
|---|
| 5859 | code before calling the parser (next to
|
|---|
| 5860 | <strong>LIBXML_TEST_VERSION</strong> is a fine place).</li>
|
|---|
| 5861 | </ol>
|
|---|
| 5862 |
|
|---|
| 5863 | <p>Following those steps should work. It worked for some of my own code.</p>
|
|---|
| 5864 |
|
|---|
| 5865 | <p>Let me put some emphasis on the fact that there is far more changes from
|
|---|
| 5866 | libxml 1.x to 2.x than the ones you may have to patch for. The overall code
|
|---|
| 5867 | has been considerably cleaned up and the conformance to the XML specification
|
|---|
| 5868 | has been drastically improved too. Don't take those changes as an excuse to
|
|---|
| 5869 | not upgrade, it may cost a lot on the long term ...</p>
|
|---|
| 5870 |
|
|---|
| 5871 | <h2><a name="Thread">Thread safety</a></h2>
|
|---|
| 5872 |
|
|---|
| 5873 | <p>Starting with 2.4.7, libxml2 makes provisions to ensure that concurrent
|
|---|
| 5874 | threads can safely work in parallel parsing different documents. There is
|
|---|
| 5875 | however a couple of things to do to ensure it:</p>
|
|---|
| 5876 | <ul>
|
|---|
| 5877 | <li>configure the library accordingly using the --with-threads options</li>
|
|---|
| 5878 | <li>call xmlInitParser() in the "main" thread before using any of the
|
|---|
| 5879 | libxml2 API (except possibly selecting a different memory allocator)</li>
|
|---|
| 5880 | </ul>
|
|---|
| 5881 |
|
|---|
| 5882 | <p>Note that the thread safety cannot be ensured for multiple threads sharing
|
|---|
| 5883 | the same document, the locking must be done at the application level, libxml
|
|---|
| 5884 | exports a basic mutex and reentrant mutexes API in <libxml/threads.h>.
|
|---|
| 5885 | The parts of the library checked for thread safety are:</p>
|
|---|
| 5886 | <ul>
|
|---|
| 5887 | <li>concurrent loading</li>
|
|---|
| 5888 | <li>file access resolution</li>
|
|---|
| 5889 | <li>catalog access</li>
|
|---|
| 5890 | <li>catalog building</li>
|
|---|
| 5891 | <li>entities lookup/accesses</li>
|
|---|
| 5892 | <li>validation</li>
|
|---|
| 5893 | <li>global variables per-thread override</li>
|
|---|
| 5894 | <li>memory handling</li>
|
|---|
| 5895 | </ul>
|
|---|
| 5896 |
|
|---|
| 5897 | <p>XPath has been tested for threaded usage on non-modified document
|
|---|
| 5898 | for example when using libxslt, but make 100% sure the documents
|
|---|
| 5899 | are accessed read-only !</p>

|
|---|
| 5980 | <p>While loading the XML file into an internal DOM tree is a matter of
|
|---|
| 5981 | calling only a couple of functions, browsing the tree to gather the data and
|
|---|
| 5982 | generate the internal structures is harder, and more error prone.</p>
|
|---|
| 5983 |
|
|---|
| 5984 | <p>The suggested principle is to be tolerant with respect to the input
|
|---|
| 5985 | structure. For example, the ordering of the attributes is not significant,
|
|---|
| 5986 | the XML specification is clear about it. It's also usually a good idea not to
|
|---|
| 5987 | depend on the order of the children of a given node, unless it really makes
|
|---|
| 5988 | things harder. Here is some code to parse the information for a person:</p>
|
|---|
| 5989 | <pre>/*
|
|---|

|---|

|
|---|
| 6030 | }</pre>
|
|---|
| 6031 |
|
|---|
| 6032 | <p>Here are a couple of things to notice:</p>
|
|---|
| 6033 | <ul>
|
|---|
| 6034 | <li>Usually a recursive parsing style is the more convenient one: XML data
|
|---|
| 6035 | is by nature subject to repetitive constructs and usually exhibits highly
|
|---|
| 6036 | structured patterns.</li>
|
|---|
| 6037 | <li>The two arguments of type <em>xmlDocPtr</em> and <em>xmlNsPtr</em>,
|
|---|
| 6038 | i.e. the pointer to the global XML document and the namespace reserved to
|
|---|
| 6039 | the application. Document wide information are needed for example to
|
|---|
| 6040 | decode entities and it's a good coding practice to define a namespace for
|
|---|
| 6041 | your application set of data and test that the element and attributes
|
|---|
| 6042 | you're analyzing actually pertains to your application space. This is
|
|---|
| 6043 | done by a simple equality test (cur->ns == ns).</li>
|
|---|
| 6044 | <li>To retrieve text and attributes value, you can use the function
|
|---|
| 6045 | <em>xmlNodeListGetString</em> to gather all the text and entity reference
|
|---|
| 6046 | nodes generated by the DOM output and produce an single text string.</li>
|
|---|
| 6047 | </ul>
|
|---|
| 6048 |
|
|---|
| 6049 | <p>Here is another piece of code used to parse another level of the
|
|---|
| 6050 | structure:</p>

| 6103 | <p>Once you are used to it, writing this kind of code is quite simple, but
|
|---|
| 6104 | boring. Ultimately, it could be possible to write stubbers taking either C
|
|---|
| 6105 | data structure definitions, a set of XML examples or an XML DTD and produce
|
|---|
| 6106 | the code needed to import and export the content between C data and XML
|
|---|
| 6107 | storage. This is left as an exercise to the reader :-)</p>

| 6109 | <p>Feel free to use <a href="example/gjobread.c">the code for the full C
|
|---|
| 6110 | parsing example</a> as a template, it is also available with Makefile in the

| 6111 | Gnome SVN base under libxml2/example</p>
