Checking whether textfield has date validation

Good morning everyone,

Scenario I have two fields: A: a textfield (nos pecific layout set) , B: a textfield set to a date layout.

I'm looping through the fields for reasons, and am looking for a boolean check where B results in true (fields with date layout) and A results in false.

Thank you in advance for any trouble to be taken,

Sincerely,

Wardenburg
