本文介绍了一个使用TinyXML库解析XML字符串的例子。通过具体代码演示了如何解析不同类型的XML数据，并展示了如何利用TinyXML进行属性查询及节点遍历。

1.下载xml源代码：github上面 clone

地址：https://github.com/aughey/tinyxml/

2.下来以后自己make一下主要的就几个头文件和源文件

3.测试案例

4.编译成静态库： ar rv libxml.a *.o

5. 测试案例运行: g++ -o test test.o -L./ -lxml

6.问题：对于main程序，先编译成目标文件，最后链接成库，不能一步做完

主要过程

#include <string>
#include "tinyxml.h"
#include "myxml.h"
#include <assert.h>
