Edit XML with grid

[donbasil]

Hi,
Im new to this forum. I was hoping for help.
i have an XML file :

<root>

    <node1 a=".." b="..">

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

    </node1>

<node1 a=".." b=".."> 

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

    </node1>

<node1 a=".." b=".."> 

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

       <node2 x=".." y=".." z=".." w=".." />

    </node1>



</root>

im having trouble editing it.. i was thinking of having a dropdownlist to choose the right "a" attribute from the first node, then to show all of the node2 attributes (x y z w) in a datagrid so i can edit and delete it.

any code or any sample for the same issue would be REALLY great.
thank you a lot!
