解析xml文件为：

 <list><vouchlist><game id="4" type="1" ishot="1" name="愤怒的小鸟0"/><game id="2" type="1" ishot="1" name="愤怒的小鸟1"/><game id="3" type="1" ishot="1" name="愤怒的小鸟2"/><game id="6" type="1" ishot="1" name="五子棋"/><game id="7" type="1" ishot="1" name="愤怒的小鸟3"/><game id="8" type="1" ishot="1" name="愤怒的小鸟10"/></vouchlist><netlist><game id="4" type="1" ishot="1" name="愤怒的小鸟4"/><game id="2" type="1" ishot="1" name="愤怒的小鸟9"/><game id="3" type="1" ishot="0" name="愤怒的小鸟5"/><game id="6" type="1" ishot="1" name="愤怒的小鸟8"/><game id="7" type="1" ishot="1" name="愤怒的小鸟6"/><game id="8" type="1" ishot="1" name="愤怒的小鸟7"/></netlist><locallist/></list>
