Yes now one is looking fro help but many might use it as a “template” for their problems.
To be fair this problem is actually well suited for a java snippet (or column expressions) as basic business rules switches are sometimes non-trivial to do in KNIME and the code might be more readable than a complex set of nodes.
And the core “trick” of this challenge to solve it in a generalized way, is the regex replace with “\D” anyway.
True that. Interesting insight!

See you all tomorrow for a new challenge!
Nice challenge. Two nodes - first to create the table, second to do the job.
