JMeter Regular Expression to extract number

Question

I want to extract letters-number from response data and tried few regex but none are working.

Eg the response data (json) will contain something like:

"sessionId":"WC-123"

And I want to extract value of sessionId ie WC-123 and store it in variable so that it can be used in other tests.

The format of sessionId will not change. It's WC-(Number) .

Answer 1
