bageler seems to be looking for something more complicated that that, I'm afraid - that would simply give 
foo
->bar
->narf

I don't know if this is possible without recursion...being lazy, I'd personally use a recursive "GetChildren($id)" routine which greps for the parent $id and pushes the returned list onto itself - terribly inefficient (as you'd be grepping the list for every element), but easier to code :)

Cheers,
Ben.
