Regular expression - excluding a character

Question

Here is an example:

s="[email protected]"

s.match(/+[^@]*/)

Result => "+subtext"

The thing is, i do not want to include "+" in there. I want the result to be "subtext", without the +

Answer 1

You can use parentheses in the regular expression to create a match group:

s="[email protected]"
s =~ /\+([^@]*)/ && $1
=> "subtext"

Answer 2

You could use a positive lookbehind assertion, which I believe is written like this:

s.match(/(?<=\+)[^@]*/)

EDIT: So I just noticed this is a Ruby question, and I don't know if this feature is in Ruby (I'm not a Ruby programmer myself). If it is, you can use it; if not... I'll delete this.
