I use xslt for a generic xml processing language. 
It is just an xml version of scheme, dsssl. 

The issue is defining rules. A perl implementation of xslt should allow
you to call native perl functions if needed.

Ok. That makes sense. The xslt would be used to match patterns in the
data stream for finding the packages to transform in the beginning.
