This may be a job for perl or python.  Both have XML parsers;
in perl and I assume python these can be up with a bit of work 
to pass everything through and let you fiddle with just the 
pieces you want.  If the incoming data was generated by a 
machine it's quite likely sufficiently regular that you don't 
even need to use the XML parser, just pattern-match for the
tags you care about. This will run faster and be less work
to write. -Tim
