| <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="http://xmlsoft.org/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> |
