Tinyxml解析xml优化（vc6.0调试ok）

发现现在网上现有用tinyxml 工具用c、c++写的xml解析工具用起来有点不方便，如是自己优化优化了一下：

所解析的xml文档如下：

<?xml version="1.0" encoding="utf-8" ?><covergae Name="ne500e" statement="80%"><Folder Name="release" path="D:\Release"><Folder Name="product" path="D:\Release\product"><Folder Name="8090" path="D:\product\8090"><Folder Name="app1" path="D:\Release\product\8090\app1"/><Folder Name="app2" path="D:\Release\product\8090\app2"/><Folder Name="app3" path="D:\Release\product\8090\app3"/><Folder Name="app4" path="D:\Release\product\8090\app4"/><Folder Name="app5" path="D:\Release\product\8090\app5"/><Folder Name="app6" path="D:\Release\product\8090\app6"/><Folder Name="app7" path="D:\Release\product\8090\app7"/><Folder Name="app8" path="D:\Release\product\8090\app8"/><Folder Name="app9" path="D:\Release\product\8090\app9"/><Folder Name="app10" path="D:\Release\product\8090\app10"/><Folder Name="app11" path="D:\Release\product\8090\app11"/><Folder Name="app12" path="D:\Release\product\8090\app12" value="1024"/></Folder></Folder></Folder></covergae>

 

最后输出：

Name: Name value: app12
1024
