Binding Treeview control to XML

1. the XML format is as follows:

<? XML version = "1.0" encoding = "UTF-8"?>
<Root name = "Digital rainwater" IMG = "image \ home.gif">
<Subroot name = "East China" IMG = "image \ resource_go.gif" nos = "1">
<Contont url = "1.html"> General info </contont>
<Contont url = "1.html"> person </contont>
<Contont url = "1.html"> nation </contont>
<Contont url = "1.html"> area </contont>
</Subroot>
<Subroot name = "North China" IMG = "image \ crm.gif" nos = "2">
<Contont url = "1.html"> original data </contont>
<Contont url = "1.html"> dairly Report </contont>
<Contont url = "1.html"> diary </contont>
<Contont url = "1.html"> relationship </contont>
</Subroot>
<Subroot name = "South China" IMG = "image \ salary.gif" nos = "3">
<Contont url = "1.html"> Dynamic Data </contont>
<Contont url = "1.html"> Information </contont>
</Subroot>
