Match but don't include in result using regex
c#, regex
Solution
A non-capturing group (not found in the match groups) is denoted as (?:). So,
(?:(?:kl(?:\.)?|at)?([0-1][0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?)
But you regexp seems to be wrongly structured from the outset. You don't capture the minutes.
Problem
I am trying to match a group in regex but I don't want this group to be in the final result. For example: `((kl(\.)?|at)?``([0-1][0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?)` Running the above expression on `at 12:25` should return `12:25`. Is there any way to do this? I tried using: `(?:((kl(\.)?|at)? )([0-1][0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?)` But that's no difference. Then I tried `(?<!(?:((kl(\.)?|at)? )([0-1][0-9]|2[0-3]):[0-5][0-9](:[0-5][0-9])?)` But that returned an empty result. I am using the expression in C#.
