Regular Expressions, Checking for a range of occurrences
- by gmcalab
I have a phone number I want to match against a regular expression.
The format of the phone number must match this:
(123) 123-4567 x12345
The extension is optional. Also the extension must contain 1-5 numbers.
Below is a regular expression I wrote that works.
^\(\d{3}\) \d{3}-\d{4}( x\d\d?\d?\d?\d?)?$
I was wondering if there is a better way to check for the extension instead of
x\d\d?\d?\d?\d?
Can I say 1-5 occurrences of \d instead of the above some how ?
