RegEx to select everything between two characters?

I am trying to write a regex that selects everything between two characters.

For example, when the regex encounters a '§' I want it to select everything after the '§' sign, up until the point that the regex encounters a ';'. I tried with a lookbehind and lookahead, but they don't really do the trick.

So for example " § 1-2 bla; " should return " 1-2 bla".

Any help would be greatly appreciated!
