Hello all,

I’m curious if anyone can help me troubleshoot a regular expression customization. I notice that the default credit card regex also pulls in ORCID ID numbers, which have the same format of four groups of four numbers separated by dashes. I’ve been experimenting with a regex that uses a negative look behind to exclude a few common combinations of ORCID prefixes in email signatures (like orcid.org, ORCID-ID:, etc). This regex works to exclude ORCIDs but include CCNs in testers like regex101.com. But when I put it in ePADD I get 0 results of any kind. Any insights are appreciated!

(?<!orcid\.org\/\s|orcid\.org\/|ORCID-ID:\s|ORCID-ID:)[0-9]{4}[-. ][0-9]{4}[-. ][0-9]{4}[-. ][0-9]{4}


Best,

Jamie

Hi Jamie,

ePADD uses a fairly limited regular expression engine, so it couldn't use that regex. I have changed this, and your regex is now used correctly. This fix will be included in the next ePADD release.

If you like, I can send you a pre-release version to try.

Best wishes

Jochen
