Regex for extraction numbers?

Question

As i'm really bad in REGEX, I'm looking for some help here. a string can be of the following two formats:

 1. id://3
 2. id://3/1

How can i check if one of the two formats is available (because there's e.g. id://next – id + strings – as well) and how can i extract in the first case the "3" and the second case the "3" and "1" in separate variables? the numbers can be anything (3,1 is just an example).

thanks in advance!

What about `2. id://3/asd/1` ? should it still match 3/1 ? – Nir Alfasi Sep 07 '14 at 16:31 — Nir Alfasi, Sep 07 '14 at 16:31

You can use this regex:

\bid:\/.*?\/(\d+)\b(?!\/)

thanks. and how can i extract the variables? – trnc Sep 07 '14 at 16:31
That is available in matched group #1. In Java you can use `String r = input.replaceFirst("^id:/.*?/(\\d+)\b(?!/).*$" "$1");` – anubhava Sep 07 '14 at 16:48
