Try

    [0-9]{3}\-[0-9]{3}(&P|P)?

Subject:  Problem with regular expression with Xquery


Hello,

 

The following problem has me stumped, and I would be grateful for any help.

 

I am using a regular expression to test if a document number is correct. The number can end with either 'P,' '&P,' or it may not have an ending value outside of the regular number.

 

For example, if a valid document number was 503-302, it could be 503-302P, 503-302&P, or just 503-302.

 

The incorrect regular expression so far is: [0-9]{3}\-[0-9]{3}&P|P.

 

This expression correctly finds 503-302P and 503-302&P, but of course fails to find 503-302. I've tried putting in other 'or' conditions at the end [e.g., |\s], but nothing has worked out.

 

Thank you again for your time and help.

 

Sincerely,

 

Kenneth Dougherty
