What expression do I use to grab between the 2 comments? I've tried everything but cant come up with anything...

[Roger_Ramjet]

Use explode() to split it up into an array of strings, the bit you want will be the middle of 3. Be easier if the comments were identical but you can just use <!---dsc_ as the break point ans chop off the rest of the comment later.

Well, you obviously haven't tried everything, because that's an infinite set that includes something that works 🙂

preg_match('/<!--dsc_begin-->(.*)<!--dsc_end-->/s', $wodge_of_text, $match);

Let me guess, you were trying to use ereg()? You don't mention if there may be more than one such section. If there is, and you want all of them, you want to use preg_match_all() and (.*?) instead of (.) - in fact, just to be on the safe side, use (.?) anyway.
