用什么控件能把一个XML文件的数据输出成如下格式.
<Nav>
<Root   Title= "AAA ">
    <Item   href= "111 "> X1 </Item>
    <Item   href= "111 "> X2 </Item>
    <Item   href= "111 "> X3 </Item>
</Root>
<Root   Title= "BBB ">
    <Item   href= "111 "> Y1 </Item>
    <Item   href= "111 "> Y2 </Item>
    <Item   href= "111 "> Y3 </Item>
</Root>
<Root   Title= "CCC ">
    <Item   href= "111 "> Z1 </Item>
    <Item   href= "111 "> Z2 </Item>
    <Item   href= "111 "> Z3 </Item>
</Root>
</Nav>

我自己建的一个XML   目的是为了存储一个二级分类或导航.可能不合理请指出.
要输出如下格式.就是一个NAVBAR  


AAA   (这个是标题点击会展开)
X1(这个是链接)
X2
X3
BBB
Y1
Y2
Y3
CCC
Z1
Z2
Z3
