Title: Works great

This is exactly what I needed. I work in books, and despite standards, people enter ISBNs in a variety of combinations of numbers and dashes. This captures them all. I simplified it for my needs as follows: (([0-9Xx][-]*){13}|([0-9Xx][-]*){10}) Note: To "Regexp user" below. You can't validate an ISBN with regex. You need math.


Title: It doesn't work

This expression doesn't work. It matches valid ISBN numbers, but it also matches ANY string having AT LEAST 10 characters and an arbitrary number of dashes and spaces. Cannot be used to check for invalid ISBN numbers
