A regular expression solution:

import re
s = """3aae5d0-1: Parent Block for 1,1,19169280:8192 (block 1,1,114688:8192)
--\n3aae5d0-1:
magic         0xdeaff2fe         mark_cookie
0x0000000000000000\ngpal-3aae5d0-1:         super.status
3        super.cookie          390781895\ngpal-3aae5d0-1:
 cg_xth                  0"""
pattern = re.compile(r"""
\( # open paren
