C++中解析XML tinyXML2

 <?xml version="1.0"?>
 <scene name="Depth">
     <node type="camera">
         <eye>0 10 10</eye>
         <front>0 0 -1</front>
         <refUp>0 1 0</refUp>
         <fov>90</fov>
     </node>
     <node type="Sphere">
         <center>0 10 -10</center>
         <radius>10</radius>
     </node>
     <node type="Plane">
         <direction>0 10 -10</direction>
         <distance>10</distance>
     </node>

 </scene>
 上述为XML 文俭
 下述为解析
