?

生成上面树的XML:

<root>
? <leafs mark="普通用户d">
??? <ID>20120804071540</ID>
??? <parentID/>
??? <name>普通用户d</name>
??? <leaf mark="用户组1">
????? <ID>20120804071541</ID>
????? <parentID>20120804071540</parentID>
????? <name>用户组1</name>
??? </leaf>
??? <leaf mark="用户组2">
????? <ID>20120804071542</ID>
????? <parentID>20120804071540</parentID>
????? <name>用户组2</name>
??? </leaf>
? </leafs>
? <leaf mark="管理员">
??? <ID>20120804072044</ID>
??? <parentID/>
??? <name>管理员</name>
? </leaf>
</root>
