I’ve not done much RegEx, so I’m having issues coming up with a good RegEx for this script.

Here are some example inputs:

document:ASoi4jgt0w9efcZXNDOFzsdpfoasdf-zGRnae4iwn2, file:90jfa9_189204hsfiansdIASDNF, pdf:a09srjbZXMgf9oe90rfmasasgjm4-ab, spreadsheet:ASr0gk0jsdfPAsdfn

And here’s what I’d want to match on each of those examples:
ASoi4jgt0w9efcZXNDOFzsdpfoasdf-zGRnae4iwn2, 90jfa9_189204hsfiansdIASDNF, a09srjbZXMgf9oe90rfmasasgjm4-ab, ASr0gk0jsdfPAsdfn

What would be the best and perhaps simplest RegEx to use for this? Thanks!

    .*:(.*) should get you everything after the last colon in the string as the value of the first group (or second group if you count the ‘match everything’ group).

    An alternative would be [^:]*$ which gets you all characters at the end of the string up to but not including the last character in the string that is a colon.
