Hi there,

I want to match the a, b, c in the following string: "[[a]]  [[b]] [[c]]"

I use RegExp with this pattern:"/\\[\\[(.*)\\]\\]/";

But this allway gives me: a]] [[b]] [[c

The flags g, m didn't change anything.

How must the pattern looks like, to find the innner values?

Quantifiers are "greedy" by default in regexps (both Java and JavaScript). You want a "reluctant" (non-greedy) quantifier here, so "\\[\\[(.*?)\\]\\]"

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/RegExp#quantifiers and https://docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html#reluc

Either that or (if that fits your problem-space) match "everything but a closing square bracket" instead of "everything": "\\[\\[([^]]*)\\]\\]"
