You need to use a more sophisticated algorithm - building up trees of potential matches, backtracking in some cases, etc. Why re-invent the wheel? Just use the regex library, where that is already done.

Some problems generate extraordinarily ugly regexes, which are then hard-to-debug. Some problems are perfectly suited to regexes. Jules
