matching multiple regexs to a single line...

Wouldn't it be a simpler and more readily maintainable design drop the
regex_ids and use a list of tuples where the first element is a rgx
and the second element is an action?  In your version you have to
maintain a dictionary and a list, as well as (somewhat superfluous)
regex ids.

import re                                         # you do want the re wrapper, not sre
lines = map(str,range(3))                         # some dummy lines for testing
handler1 = handler2 = handler3 = lambda x: None   # some very dumb handlers

regexs = (
    ( re.compile( r'regex1' ), handler1 ),
    ( re.compile( r'regex2' ), handler2 ),
    ( re.compile( r'regex3' ), handler3 ),
    )

for line in lines :
   for (rgx, action) in regexs:
      m = rgx.match( line )
      if m: action(m)
