99 <p>Libxml is the XML C library developed for the Gnome project. XML itself
100 is a metalanguage to design markup languages, i.e. text language where
101 semantic and structure are added to the content using extra "markup"
102 information enclosed between angle brackets. HTML is the most well-known
103 markup language. Though the library is written in C <a href="python.html">a
104 variety of language bindings</a> make it available in other environments.</p>
105 <p>Libxml2 implements a number of existing standards related to markup

138 <p>In most cases libxml tries to implement the specifications in a relatively
139 strictly compliant way. As of release 2.4.16, libxml2 passes all 1800+ tests
140 from the <a href="http://www.oasis-open.org/committees/xml-conformance/">OASIS XML Tests
142 <p>To some extent libxml2 provides support for the following additional
143 specifications but doesn't claim to implement them completely:</p>
145 <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>
146 it doesn't implement the API itself, gdome2 does this on top of

159 <p>A partial implementation of XML Schemas is being worked on but it would be
160 far too early to make any conformance statement about it at the moment.</p>
161 <p>Libxml2 is known to be very portable, the library should build and work
162 without serious troubles on a variety of systems (Linux, Unix, Windows,
163 CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, ...)</p>
