This actually from a change event, but an itemClicked one is very
similar ...
(It presumes that you use xml as the dataprovider for the tree, and
listen for the event by adding 'change=onTreeChange(event)' in your
trees attributes )

private function onTreeChange(event:ListEvent):void
{
var targetTree:Tree = event.target as Tree; 

 var item:XML = XML(targetTree.selectedItem);
 
 var theParent:XML = item.parent();

}

It does seem a bit unintuitive to get an XML object, but normally that
works fine for what you're likely to want to do, I've found.

Hope that's enough to be helpful!
