RE: [PHP] Re: Ignore Tags

I didn't check out your source, but in terms of a regex that only matches
items not surrounded by some special tag, what about negative lookaheads and
lookbehinds, like:

(?<!\[specialtag\])REST_OF_YOUR_REGEX(?!\[specialtag\])

I've not used them in PHP, but just a quick thought that might help.
