Get the position of the last slash in the array value, run a in_array(), get
the parent ID...
That is pretty inefficient, so once you got the information about the parnt
of each node, store it in the DB (I suppose you're using a DB backend).
When fetching from the DB, rebuild the tree (remember you can use nested
arrays as trees), and everything will be much easier from there.
