Thanks for the quick reply. I was so neck-deep in this stuff all day I didn't explain it well. For example, the first couple lines of the output file (as related to the original XML I posted) would be this:

inside-hosts
inside-hosts.catchall 10.0.0.0/8
inside-hosts.catchall 192.168.0.0/16
inside-hosts.By Function
inside-hosts.By Function.B2B 192.168.0.0/16
inside-hosts.By Function.B2B 192.167.0.0/16
inside-hosts.By Function.B2B 192.166.0.0/16
inside-hosts.By Function.DMZ 192.168.0.1/16
... etc ...
inside-hosts.By Function.Infrastructure
inside-hosts.By Function.Infrastructure.Firewalls 192.168.0.1/16
inside-hosts.By Function.Infrastructure.Firewalls 192.168.0.2/16

My biggest issue is figuring out how to loop through the XML and parse out the name and the IP ranges and create the  name.name.name <tab> IP/range structure.
