I've tried this:
Code:
Story URL: https://www.fanfiction.net/s/[0-9][0-9][0-9]+/|Story URL: http://www.fanfiction.net/s/[0-9][0-9][0-9]+/
I don't understand the number in the selection after story_id.
The only reason I inserted the 9 was because it was in your example image earlier.
If this is wrong, then I would appreciate some help.
Also some of the urls are http and some are https.
