•Variable type: Short Text
•Document with variables defined and set to Visible
•Regular expressions used in the action code for the regexp string:
•an e-mail address: e.g. john.doe@mycompany.com
^([a-zA-Z0-9.\-]+)@([a-zA-Z0-9.\-]+)$
•a license plate: e.g. 1 ABC 234
^(([0-9]{0,1}[ ]*[A-Z]{3}[ ]*[0-9]{3})|([0-9]{3}[ ]*[A-Z]{3}))$
•a bank account number: e.g. 123-4567891-23
^[0-9]{3}-[0-9]{7}-[0-9]{2}$
•a phone number: e.g. 123 45 678
^[0-9]{3}[ ][0-9]{2}[ ][0-9]{3}$
