how to match something with regExp between roundbrackets

Question

I have this:

var regExp:RegExp = new RegExp("((.*?)%)");

and want everything between the ( and the %) the string looks like this: (-24%)

I now get a return back "(-24" and have searched for a long time to find a solution but didn't find any.

Answer 1

You need to escape the parentheses

use:

var regExp:RegExp = new RegExp("\\((.*?)%\\)");

for example, given the string "(-24%)", this regex will capture "-24"

edited my bad. forgot when creating the regex that way it needs double escape. fixed

Answer 2

You're probably going to have to do something with lookahead, lookbehind if you need to find what's inside something with a regexp.

Alternatively you could just trim the results after you get them.
