We need to mimic “AND” functionality using look ahead expression (?=expr). See the construct below:
^(?=.*?expr)(?=.*?expr)(?=.*?expr).*$This functionality works in Java/Phyton/Perl/PHP and many other languages, however it might not be available in JavaScript. Check latest JS specification and let me know if this has changed.
EXAMPLE:
^(?=.*?(\b\d\d\d-\d\d\d\b))(?=.*?(3D))(?=.*?Demo{1}).*$Will match:111-234 sometext 3D Demo
Will not match:1113-223 sometext 3D Demo
If you would not use \b at the end and start of the expression, it would also match the above line.
