228 <p>Libxml2 is the XML C parser and toolkit developed for the Gnome project
229 (but usable outside of the Gnome platform), it is free software available
230 under the
<a href=
"http://www.opensource.org/licenses/mit-license.html">MIT
231 License
</a>. XML itself is a metalanguage to design markup languages, i.e.
232 text language where semantic and structure are added to the content using
233 extra
"markup" information enclosed between angle brackets. HTML is the most
234 well-known markup language. Though the library is written in C
<a href=
"python.html">a variety of language bindings
</a> make it available in
235 other environments.
</p>
236 <p>Libxml2 is known to be very portable, the library should build and work
237 without serious troubles on a variety of systems (Linux, Unix, Windows,
238 CygWin, MacOS, MacOS X, RISC Os, OS/
2, VMS, QNX, MVS, VxWorks, ...)

</a> Working Draft

263 <p>In most cases libxml2 tries to implement the specifications in a
264 relatively strictly compliant way. As of release
2.4.16, libxml2 passed all
265 1800+ tests from the
<a href=
"http://www.oasis-open.org/committees/xml-conformance/">OASIS XML Tests
267 <p>To some extent libxml2 provides support for the following additional
268 specifications but doesn't claim to implement them completely:
</p>
269 <ul><li>Document Object Model (DOM)
<a href=
"http://www.w3.org/TR/DOM-Level-2-Core/">http://www.w3.org/TR/DOM-Level-
2-Core/
</a>
270 the document model, but it doesn't implement the API itself, gdome2 does
271 this on top of libxml2
</li>
272 <li><a href=
"http://www.cis.ohio-state.edu/rfc/rfc959.txt">RFC
959</a> :
273 libxml2 implements a basic FTP client code
</li>
274 <li><a href=
"http://www.cis.ohio-state.edu/rfc/rfc1945.txt">RFC
1945</a> :
275 HTTP/
1.0, again a basic HTTP client code
</li>
276 <li>SAX: a SAX2 like interface and a minimal SAX1 implementation compatible
277 with early expat versions
</li>
279 <p>A partial implementation of
<a href=
"http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/">XML Schemas Part
280 1: Structure
</a> is being worked on but it would be far too early to make any
281 conformance statement about it at the moment.
