说明：  Libxml2 是一个xml c语言版的解析器，本来是为Gnome项目开发的工具，是一个基于MIT License的免费开源软件。它除了支持c语言版以外，还支持c++、PHP、Pascal、Ruby、Tcl等语言的绑定，能在Windows、Linux、Solaris、MacOsX等平台上运行。功能还是相当强大的，相信满足一般用户需求没有任何问题。
(Libxml2 is an xml parser of c language version, was originally developed for the Gnome project tools, based on the MIT License free open source software. In addition to the support of c language version also supports c++, PHP, Pascal, Ruby, Tcl language bindings can be run on Windows, Linux, Solaris, MacOsX platform. Function is still quite strong, I believe that to meet the needs of the average user without any problems.)
