libxml2的是为Gnome项目(但可用的GNOME平台外)开发的XML C解析器和工具包,它是免费软件,可根据MIT许可。 XML本身是一种元语言设??计的标记语言,即文字语言的语义和结构都使用额外的“标记”之间的尖括号内的信息内容添加到。 HTML是最知名的标记语言。 虽然库是用C写各种语言绑定 ,在其他环境中亦能使用。
libxml2的是已知的非常便携,库应建立和各种系统(Linux,Unix系统,Windows中,Cygwin的,是MacOS,MacOS X系统,RISC OS,OS / 2,VMS,QNX,MVS,VxWorks的工作没有严重的问题... ...)

在大多数情况下的libxml2试图实现在一个比较严格的兼容的方式的规范。 版本2.4.16,libxml2的OASIS XML测试通过,从1800 +的测试。
在一定程度上的libxml2提供下列额外规格的支持,但不主张完全实现它们:
- 文档对象模型(DOM) http://www.w3.org/TR/DOM-Level-2-Core/文档模型,但还没有实现的API本身,gdome2这个libxml2的顶部
- RFC 959 :libxml2的实现一个基本的FTP客户端代码
- RFC 1945年 :HTTP/1.0的,再一个基本的HTTP客户端代码
- SAX:像SAX2的接口和一个最小的SAX1实施与早期版本的外籍兼容
一个部分实现的XML架构第1部分:结构正在工作,但它会还为时过早,目前关于它的任何一致性声明。
单独的文件:
- 提供libxml2的执行XSLT 1.0和共同喜欢的EXSLT扩展的libxslt页
- gdome2页 :libxml2的一个标准DOM2的实施
- XMLSec页 :实施libxml2的W3C XML数字签名
- 还检查为更多相关的和积极的项目的相关链接部分。

"Programmingwith libxml2 is like the thrilling embrace of an exotic stranger." MarkPilgrim
Libxml2 is the XML C parser and toolkit developed for the Gnome project(but usable outside of the Gnome platform), it is free software availableunder the MITLicense. XML itself is a metalanguage to design markup languages, i.e.text language where semantic and structure are added to the content usingextra "markup" information enclosed between angle brackets. HTML is the mostwell-known markup language. Though the library is written in C a variety of language bindings make it available inother environments.
Libxml2 is known to be very portable, the library should build and workwithout serious troubles on a variety of systems (Linux, Unix, Windows,CygWin, MacOS, MacOS X, RISC Os, OS/2, VMS, QNX, MVS, VxWorks, ...)
Libxml2 implements a number of existing standards related to markuplanguages:
- the XML standard: http://www.w3.org/TR/REC-xml
- Namespaces in XML: http://www.w3.org/TR/REC-xml-names/
- XML Base: http://www.w3.org/TR/xmlbase/
- RFC 2396 : Uniform Resource Identifiers http://www.ietf.org/rfc/rfc2396.txt
- XML Path Language (XPath) 1.0: http://www.w3.org/TR/xpath
- HTML4 parser: http://www.w3.org/TR/html401/
- XML Pointer Language (XPointer) Version 1.0: http://www.w3.org/TR/xptr
- XML Inclusions (XInclude) Version 1.0: http://www.w3.org/TR/xinclude/
- ISO-8859-x encodings, as well as rfc2044 [UTF-8] and rfc2781 [UTF-16] Unicode encodings, and more if using iconv support

- W3C xml:id Working Draft 7 April 2004
In most cases libxml2 tries to implement the specifications in arelatively strictly compliant way. As of release 2.4.16, libxml2 passed all1800+ tests from the OASIS XML TestsSuite.
To some extent libxml2 provides support for the following additionalspecifications but doesn't claim to implement them completely:
- Document Object Model (DOM) http://www.w3.org/TR/DOM-Level-2-Core/ the document model, but it doesn't implement the API itself, gdome2 does this on top of libxml2
- RFC 959 : libxml2 implements a basic FTP client code
- RFC 1945 : HTTP/1.0, again a basic HTTP client code
- SAX: a SAX2 like interface and a minimal SAX1 implementation compatible with early expat versions
A partial implementation of XML Schemas Part1: Structure is being worked on but it would be far too early to make anyconformance statement about it at the moment.
Separate documents:
- the libxslt page providing an implementation of XSLT 1.0 and common extensions like EXSLT for libxml2
- the gdome2 page : a standard DOM2 implementation for libxml2
- the XMLSec page: an implementation of W3C XML Digital Signature for libxml2
