Hi I'm creating a registration page. It has "Enter License Number:" i want to create a validation expression that if the user type a wrong format in that field. The form will not be submitted. It must be corrected before they submitted. I dragged the "Regular Expression Validator" in my website. But they don't have a default expression for license number. I must custom the expression to have my own expression.
Now i only want to know what is the validation expression of this sample license number:
G11-11-004064 -- A Philippines sample driver's license.
LetterNumberNumber - NumberNumber - NumberNumberNumberNumberNumberNumber
Could you convert it?
Here's a regular expression editor. It's aimed towards Ruby but will do for .NET as well:
I don't know about the detailed specification of the license numbers you#re looking for, but I created a regex based on your example: ^[A-Z]\d{2}-\d{2}-\d{6}$.
You can modify it here:
The example explained:
^[A-Z]\d{2}-\d{2}-\d{6}$
^ = start of line
[A-Z] = a single upper case letter
\d{2} = any number with 2 digits
\d{6} = any number with 6 digits
$ = end of line
If you want to make sure you don't miss lower case letters starting the license use [A-Za-z] instead of [A-Z]
