How to write this field extraction using rex?

Path Finder

Hi All, I'm trying to extract the card details in  my logs. Just confused how to extract the two or more card details or thier respective fields using rex command.

Example : Visa card numbers regex is ^4[0-9]{12}(?:[0-9]{3})?$

                    JCB card numbers regex is ^(?:2131|1800|35\d{3})\d{11}$

I just want to extract the Visa and JCB fileds to check my card details. Is thier a way to create named grouped fields for the above cards using rex command in a single search?

Help me with the query guys.

Thanks in advance.

Is this what you mean?

| rex "^(?<jcb>(?:2131|1800|35\d{3})\d{11})|(?<visa>4[0-9]{12}(?:[0-9]{3})?)$"
