I have a multi-tier hash (see below) and I'd like to be "search" the hash for a given $id, and return that section, regardless of how many layers deep it is. Sort of like how xpath works?
Once I have that I'd like get ALL the children of a given node. So I
could ask for 86, and get 36, 38, 56, etc and all THEIR children.
Basically I want *all* the ID #s that are children.
