Match Sequence using RegEx After a Specified Character

Question

The initial string is [image:salmon-v5-09-14-2011.jpg]

I would like to capture the text \"salmon-v5-09-14-2011.jpg\" and used GSkinner\'s RegEx Tool

Answer 1

Use a look-behind:

(?<=:)[\w+.-]+

A look-behind (coded as (?<=someregex)) is a zero-width match, so it asserts, but does not capture, the match.

Also, your regex may be able to be simplified to this:

(?<=:)[^\]]+

which simply grabs anything between (but not including) a : and a ]
