the Gnome project. XML itself is a metalanguage to design markup languages, i.e. text language where semantic and structure are added to the content using extra "markup" information enclosed between angle brackets. HTML is the most 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 other environments.</p> <p>Libxml2 implements a number of existing standards related to markup languages:</p> <ul> <li>the XML standard: <a href="http://www.w3.org/TR/REC-xml">http://www.w3.org/TR/REC-xml</a> </li> <li>Namespaces in XML: <a href="http://www.w3.org/TR/REC-xml-names/">http://www.w3.org/TR/REC-xml-names/</a> </li> <li>XML Base: <a href="http://www.w3.org/TR/xmlbase/">http://www.w3.org/TR/xmlbase/</a> </li> <li> <a href="http://www.cis.ohio-state.edu/rfc/rfc2396.txt">RFC 2396</a> : Uniform Resource Identifiers <a href="http://www.ietf.org/rfc/rfc2396.txt">http://www.ietf.org/rfc/rfc2396.txt</a> </li> <li>XML Path Language (XPath) 1.0: <a href="http://www.w3.org/TR/xpath">http://www.w3.org/TR/xpath</a> </li> <li>HTML4 parser: <a href="http://www.w3.org/TR/html401/">http://www.w3.org/TR/html401/</a> </li> <li>most of XML Pointer Language (XPointer) Version 1.0: <a href="http://www.w3.org/TR/xptr">http://www.w3.org/TR/xptr</a> </li> <li>XML Inclusions (XInclude) Version 1.0: <a href="http://www.w3.org/TR/xinclude/">http://www.w3.org/TR/xinclude/</a> </li> <li>[ISO-8859-1], <a href="http://www.cis.ohio-state.edu/rfc/rfc2044.txt">rfc2044</a> [UTF-8] and <a href="http://www.cis.ohio-state.edu/rfc/rfc2781.txt">rfc2781</a> [UTF-16] core encodings</li> <li>part of SGML Open Technical Resolution TR9401:1997</li> <li>XML Catalogs Working Draft 06 August 2001: <a href="http://www.oasis-open.org/committees/entity/spec-2001-08-06.html">http://www.oasis-open.org/committees/entity/spec-2001-08-06.html</a> </li> <li>Canonical XML Version 1.0: <a href="http://www.w3.org/TR/xml-c14n">http://www.w3.org/TR/xml-c14n</a> and the Exclusive XML Canonicalization CR draft <a href="http://www.w3.org/TR/xml-exc-c14n">http://www.w3.org/TR/xml-exc-c14n</a> </li> </ul> <p>In most cases libxml tries to implement the specifications in a relatively strictly compliant way.
