C++ STL一一map存储小实例

map存储在xml文件中的体现是非常方便的，如下简单的xml文件实例结构

/*<Params>    <Name>xuanyin235</Name>    <Age>24</Age>    <Sex>male</Sex></Params>*/

/*<SubItems>    <Item1 Name="xuanyin235" Age="24" Sex="male" />    <Item2 Name="kitty" Age="18" Sex="female" />    <Item3 Name="Kimi" Age="13" Sex="male" /></SubItems>*/

代码存储实例如下：

运行结果：
