Sometimes I like to make a special class that saves the result:
class
(^DATASET:\s*(.+) , line)
print m.group(1))
which is ugly because of the duplication but I can't think of a nicer of way
of doing this that will allow for a lot of these sorts of cases. Any
suggestions?

How about something like:
your_regexes = [
re.compile('rx1'),
re.compile('rx2'),

Or in case you want to handle each regexp differently, you can
construct a dict {regexp : callback_function} that picks the right
action depending on which regexp matched.
One word of caution: dicts are unsorted, so if more than one
regexp can match a given line, they either need to map to
