also keep in mind that '.' does not match newlines. so you may be looking for `[.\n]*?` instead. update: I should have known that I was missing something. It seemed most out of character for merlyn to miss something like that.	[reply] [d/l]

No, the /s properly takes care of that, and your regex matches only periods and newlines. -- Randal L. Schwartz, Perl hacker	[reply]

Ok, this is beyond the scope of the initial question, but I'm curious anyways - the /o caches the Regexp so it doesn't need to be re-compiled, correct? I'm not familiar with the innards of the interpreter, but in the event we returned to this RE, wouldn't that be an (albeit extremely minimal) optimization?	[reply]

The /o does something only if there are variables in the regex. I saw no variables in that regex. -- Randal L. Schwartz, Perl hacker	[reply]
