对XML文件操作

XML具体操作实现(增加，删除，更新，导出)
XML格式：

<?xml version="1.0" encoding="GB2312"?>
<app:Users xmlns:app="uri:appraisal">
  <User id="000">
    <Name>Jeffrey</Name>
    <Sex>男</Sex>
    <UserName>Jeffrey</UserName>
    <UserID>1</UserID>
    <Department>Jeffrey</Department>
    <Working>是</Working>
    <Power>0</Power>
    <Position>1</Position>
    <Post>
    </Post>
