Xerces C++ SAX解析XML文档

关于SAX的解释，和好处，不做过多的介绍，你完全可以搜索引擎里面找到茫茫多的介绍http://baike.soso.com/v123641.htm?ch=ch.bk.innerlink；

本文的主要目的是介绍如何在自己的C++程序中利用Xerces C++ SAX解析XML文档；

1、Xerces C++下载

首先，我们需要去下载Xerces C++：http://xerces.apache.org/xerces-c/download.cgi

以上连接中给出了各种VS版本的Xerces C++的编译文件和源代码，供你下载使用。

2、在工程中引入Xerces C++

1、C/C++ 常规中：附件包含目录：引入include ；头文件

2、链接器常规中：附件包含目录：引入lib；bin；文件

3、链接器输入中：附加依赖项：引入：xerces-c_3.lib       xerces-c_static_3.lib

3、OK以上环境搭建好后，开始编码吧
