If the above format is strictly followed, this should do it,
assuming you can read the entire file into a string (s in
the example below.
TITLE_RE = re.compile( r'#\n#([^\n]*)\n#\n \n\[([^\]]*)\]\n \n',
for m in TITLE_RE.finditer( s.strip ):
title, info = m.groups()
print title, info
Error handling, and reading chunks from a large file
are left as an exercise for the reader.
Also, if the file format is at all more complex, and
maybe even in this case, I would write a parser
rather than use regular expressions.
