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.By Function.B2B 192.168.0.0/16
inside-hosts.By Function.B2B 220.127.116.11/16
inside-hosts.By Function.B2B 18.104.22.168/16
inside-hosts.By Function.DMZ 192.168.0.1/16
... etc ...
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
