[flexcoders] parsing xml recursively help.

I am just trying a simple example with trying to parse some xml. I want to be able to find what node is selected according to what is selected in a Tree component.

here is my AS:

private function getSelectedNodeFromSelectedItem( searchXML:* , selectedItem:Object ):XMLList
        {
            var foundNode:*;

            for each( var prop:* in searchXML )
            {

                if( [EMAIL PROTECTED] == [EMAIL PROTECTED] )
                {
                    foundNode = XMLList( prop );
                    break;
                }

                else if( [EMAIL PROTECTED] == "folder" )
                {
                    getSelectedNodeFromSelectedItem( prop.node );
                }
            }
            return foundNode;
        }

this is what the XML Looks like: (dataProvider to a Tree )

<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>

Say for instance you selected the 2nd child of the flash platform node. it would spit back:
<node label=somelink' id='3' type='item' feedLocation=' http://www.somelink.com' />

Say for instance you selected the root node which is a folder. it would spit back:
<node label='flash platform' id='1' type='folder' >
   <node label='www.smithaaronlee.net' id='2' type='item' feedLocation='http://www.smithaaronlee.net' />
   <node label='teguh mualim' id='3' type='item' feedLocation='http://www.capcai.com' />
</node>

It seems to be working correctly to the point where it knows that the right node is selected, but then the return value is of type [object]. I can't figure out how to get it back as a string..

From the results that are spit back from that method I will pass that value to another parsing method to just grab all the individual items (type=item) in the selected node. See what I'm going for?

Maybe I need to cast the xml into an ArrayCollection?

thanks
