Writing and Testing Regular Expressions

Regular expressions have their own syntax separate from CSPro logic. Therefore, it is recommended to write and test your regular expressions in a regular expression editor. Use any regular expression editor that supports ECMAScript (JavaScript) engine (or flavor). One such editor is regex101, just make sure you change the flavor to ECMAScript.

Example

// Matches format xxx-xxx-xxxx
if regexmatch(TELEPHONE_NUMBER, "^([0-9]{3}-){2}[0-9]{4}$") then
// ...
endif;

// Basic validation for email
if regexmatch(EMAIL, @"^[^@\s]+@[^@\s]+\.[^@\s]+$") then
// ...
endif;
