Nintex .NET Framework RegEx Extract

I'm using Nintex Workflows and running into an issue trying to extract a alphanumeric value after the word number: using RegEx Action. I have two entries in document that I'm parsing.

Today's serial is number: A12345

This line appears twice in the email and I only watch to capture the first instance. Note: The alphanumeric value changes with each email it's not static.

Currently I'm using (?<=number:\s) ([a-zA-Z0-9]+$) however it doesn't match anything. When I do (?<=number:\s)\w+ it matches the results both times.

What do I need to the working example to only collect the first match?

You could try the below regex,

(?s)^.*?number:\s([a-zA-Z0-9]+)

And get the string you want from group index 1. In (?s) dotall mode, ^ matches the start of first line only.

OR

You could use the below variable length look-behind based regex.

(?s)(?<=^.*?number:\s)[a-zA-Z0-9]+
