String matching

I've got a script which basically goes line by line through an external file, and hands it to the screen in a slightly parsed form.

I'd like to apply another bit of parsing to what's coming in though, and specifically look for a pattern matching "[[form=x]]" where x can be any number.

If that string is found, I'd like to grab the "x" part, pass it through a subroutine, and then replace the "[[" and "]]" and everything in between with a variable.

I think I can do the latter bit myself, it's just the matching the string (that is, any section of the line starting with "[[file=" and ending with "]]") and grabbing the number that I can't figure out.

Any help is much appreciated.

Update: I sorted this out myself using a regular expression. I suspected that would be the answer, but it was easier than I thought to get it working.

If anyone's interested, this is the code I used to grab the number in the [[form=]] tag:

Thanks for posting the answer. I was about to answer that I could hard code it, but what you really need were regular expressions, and I had never used them in ASP. Glad we have that on file now :-)
