Dear Perl Monks I'm looking for some ideas or tutorials or documents about working with trees. I search the web a lot but not convincing what module to used for my purplish. since usual here does not make me disappointed i came to ask for your help. my main purpose is that I want to change convert a syntactic parsed text to a tree (Possibly xml but not necessarily) and then implement the Tree Edit Distance on it. The parser output could be like this: 
(ROOT
  (S
    (NP (DT this))
    (VP (VBZ is)
      (ADVP (RB just))
      (NP (DT a) (NN test)))
    (. .)))

while i want to convert it to tree structure and then mainly use post order traversal for implementing TED algorithms. so i prefer something more convinient for labeling the nodes and finding the key nodes of the tree and/or comparing them and what so ever. All your suggestions is really appreciated. Best Regards and thanks in advance ...
