Definitely a straight-forward parsing task. The description I elided
suggests that a parser which supports regular expressions might make
the task easier. There are several candidates in that area that I am
aware of (and probably even more that I'm not), such as Yacc++, Visual
Parse++, and PCCTS. I have heard of similar tasks (for example,
networking protocols) successfully being attacked as parsing problems.
