| <p>Libxml2 is the XML C parser and toolkit developed for the Gnome project |
| (but usable outside of the Gnome platform), it is free software available |
| under the <a href="http://www.opensource.org/licenses/mit-license.html">MIT |
| License</a>. 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 is known to be very portable, the library should build and work |
| without serious troubles on a variety of systems (Linux, Unix, Windows, |
| CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks, ...)</p> |

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

| libxml2 implements a basic FTP client code</li> |
| <li><a href="http://www.cis.ohio-state.edu/rfc/rfc1945.txt">RFC 1945</a> : |
| HTTP/1.0, again a basic HTTP client code</li> |
| <li>SAX: a SAX2 like interface and a minimal SAX1 implementation compatible |
| with early expat versions</li> |
| </ul> |
| <p>A partial implementation of <a href="http://www.w3.org/TR/2001/REC-xmlschema-1-20010502/">XML Schemas Part |
| 1: Structure</a> is being worked on but it would be far too early to make any |
