If I understand you correctly, here is the relevant part (untested):
import subprocess, collections
dig = subprocess.Popen(["dig", "ns.example.com", "example.com", "axfr"],
stdout=subprocess.PIPE).stdout
# defaultdict allows the equivalent of push @{$x{$y}}, $z
cnames = collections.defaultdict(list)
ip = {}
for line in dig:
if line.startswith(';'):
continue # Skip any comments
m = re.search(r'regexp1', line)
if m:
cnames[m.group(2)].append(m.group(1)) # push ...
m = re.search(r'regexp2', line)
if m:
ip[m.group(1)] = m.group(2)
