in Python, the RE machinery returns match objects, which has methods
that let you dig out more information about the match. "captured groups"
are available via the "group" method:
m = re.search(..., line)
if m:
print "got", m.group(1)
see the regex howto (or the RE chapter in the library reference) for more
