Regex Validator

[Paul Krueger]

I'm trying to use a validator to make sure issues with "<Update Text>" in the description can't transition. The regex I think should work is this: 

^(?:(?!<Update Text>).)*$

I've also tried this:

^(?!.*<Update Text>).*$[\s\S]*

Either way, it's not working.

Hi @Paul Krueger 

Superficially, it seems you could match without the extra anchors and lookahead assertions.

<Update-Text>

I suspect that I don't completely understand what you're hoping to solve. Could you post a sample description that you believe should match?

[Paul Krueger]

Yes, that would match if that text were in there, but I need it to match when the text isn't there.

I understand. Try this:

^((?!<Update Text>).)*$

That did the trick. Thank you so much!
