Problems with Regex Matching

carlo2 — Thu, 06 Feb 2025 10:51:22 GMT

Hello, I have the following problem. I want to copy the text from a word file and then extract a number in combination with a word from this text using RegEx. For this I used the action stage "Extract Regex All Matches" from the VBO "Utility - Collection Manipulation". Unfortunately, it throws this error.

What could be the reason?

The RegEx looks like this:

(?is)^(?=.*?\bWord\w*\b).*?\K(?<Nr>\b80\d{5})(?!\d)

Could you please share the sample data here for the below line

I want to copy the text from a word file and then extract a number in combination with a word from this text using RegEx

Also try the below expression to see if you are still getting the error

(?is)^(?=.*?\bWord\w*\b).*?(?<Nr>\b80\d{5})(?!\d)
