I’m relatively inexperienced with regex but I’ve always been able to solve my issues with some googling. But I’m stumped by the code I’d need for the situation I’m currently facing.

I have a string of values with a pipe delimiter. We’ve recently added two variables to the end of the string for capture going forward, so the string will either have 6 or 8 values.

Example strings with junk values:

• unknown|yes|no|true|false|maybe
• unknown|yes|no|true|false|maybe|optional|optional

The regex I’ve written so far is: ^(.)|(.)|(.)|(.)|(.)|(.)|(.)|(.)

It captures perfectly if all 8 values are there, but doesn’t cover the 6-value string. I just can’t quite figure out the “or” statements needed to account for this. Any help would be appreciated.
