Universal parser for all xml this is very hard work. If you have already created VM, you can destroy them without removing hdd images and create custom.

Of course this is not critical feature or bug (as you wish) and I understand that parse whole xml is pretty hard.

PS:
maybe parser from virt-manager helps? It is in python too-)
