Subject: Parser as an alternative to RegExen

I'm parsing a large file, currently using compound regexen:

PREAMBLE = 'AA'
USERID = '\d{8}'
USER_HELLO = "#{PREMABLE}(#{USERID})"

Is there a simple way to do this using a parser such as ANTLR?  I've
never used one before, so if it requires a learning curve, I'll stick
to my regexen.

But if there is a cleaner way to do this, I'd certainly like to.
