in thread regex for string

It won't match what you want because the '*' quantifier is greedy, and the '?' can match 0 or 1 times. So, the '*' matches all of the it can, and the last '?' matches 0 times; so the match is successful. You have to force '*' to give something back to the rest of the regex by replacing '?' with '{1}' for example.
