How can I create a Lookbehind expression matching on a dynamic pattern? In other words, the text pattern I am trying to match in the Lookbehind statement should also be pattern matched. Example below:
I have the text:
Last flapped : 2018-05-18 07:11:06 CEST (12w3d 11:08 ago)
And I want to match the date and time after "Last flapped :". The only problem is that the number of spaces between "flapped" and the ":" can vary.
