Dynamic Treeview Binding with XML file-XBAP Application

Question

I have a XML file which has maximum three levels of child elements so i need to bind the file with TreeView in WPF for XBAP App Dynamically. Do we need to use Hierarchical template or is there any other way to get easy binding..

for example:

<TriggerList>
  <Trigger>
    <TriggerName>trig1</TriggerName>
    <TriggerSource>manual</TriggerSource>
    <TriggerInfo>
      <Alaramid>2312</Alaramid>
      <Area>area1</Area>
      <ToolType>OLF121</ToolType>
    </TriggerInfo>
  </Trigger>
</TriggerList>

I want to make this in tree view through Dynamic Binding ..
