[Bioperl-l] Question about handling ontology files

[iluminati at earthlink.net]

Here's my situation.  I have a bunch of ontologies downloaded from a 
batch run on SOURCE.  What I want to be able to do is parse these files 
so I can count the different numbers of instances of terms within all 3 
sets of ontological descriptions (biological process, cellular component 
and molecular function).  Is there something in Perl or another program 
that could help me out with this situation?  Any information that you 
have would be useful to me.  Thanks
