in thread Can't match negated words.

Hi Abigail,

I'd like to match the first '/*' and check that there's no

throw declared before it.

I think it should look something like this?

m!^/[*].*?(?:(?!throw).)*/[*]!s

I can't really understand what the '.)*' means after the throw?

You could explain it briefly could you? Thanks,

Mark.

    No, I think not, for exactly the reasons I stated. But if you're convinced you're right, by all means, use your regex. It's not my program after all.

    It doesn't make any sense at all. It's like asking what the "nd wh" in your question means. A dot means "match any character", and a star means "match the preceeding unit one or more times", but the closing parenthesis is belongs to the matching opening one.

    However, if you don't understand the most basic regexp tokens, I urge you to first learn basic regexes, before continuing asking questions.
