well, I actually need reference to the xml from where the selection occurs..

say this is the XML:

<node label='flash platform' id='1' type='folder' >
   <node label='www.somelink.net' id='2' type='item' feedLocation=' http://www.somelink.net' />
   <node label=somelink' id='3' type='item' feedLocation=' http://www.somelink.com' />
   <node label='bmx biking' id='4' type='folder' >
<node label='www.somelink.net' id='5' type='item' feedLocation=' http://www.somelink.net' />
<node label=somelink' id='6' type='item' feedLocation=' http://www.somelink.com' />
   </node>
</node>

if you select flashplatform in the tree.. it should return the entire xml structure...

VS if you select bmx biking, it would spit this out:
<node label='bmx biking' id='4' type='folder' >
   <node label='www.somelink.net' id='5' type='item' feedLocation=' http://www.somelink.net' />
   <node label=somelink' id='6' type='item' feedLocation=' http://www.somelink.com' />
</node>

now if you select an actual item( id=5) it would spit this out:
<node label='www.somelink.net' id='5' type='item' feedLocation=' http://www.somelink.net' />

The next step after getting the XML where the selection has occured, is getting all the individual items in the xml..

so if you select bmx biking, the items i'm looking for are:::
<node label='www.somelink.net' id='5' type='item' feedLocation=' http://www.somelink.net' />
<node label=somelink' id='6' type='item' feedLocation=' http://www.somelink.com' />

Or if you selected "flash platform" the items would look liek this;
<node label='www.somelink.net' id='2' type='item' feedLocation=' http://www.somelink.net' />
<node label=somelink' id='3' type='item' feedLocation=' http://www.somelink.com' />
<node label=' www.somelink.net' id='5' type='item' feedLocation='http://www.somelink.net' />
<node label=somelink' id='6' type='item' feedLocation=' http://www.somelink.com' />

i'm using this so that when you select a folder in the Tree, I can recursively get all the actual Items in the XML (type=item)...
see what I mean? so like, from the folder you've seleted and down it's tree of nodes, it should get the items in its xml..

i hope that explains it better...

or am I complicating this too much? does tree.selectedItem return the xml nodes?

thanks

Sure Aaron,

Instead of loopin, have you tried something like this?

var myNode:XML = XML(myTree.selectedItem);
