Hi again,

I'm trying to match date string. I use with 'Flavor' set to 'PCRE' to test.
I've used Negative lookbehind to NOT match anything containing numbers prior to date.

Test string:

This works perfectly in regex101, but matches nothing at all in Advanced Renamer.

Does anyone have any ideas?

This captured the required input.

I'm still learning :
