Question

i need a certain string to be in this format:
[0000] anyword

so between the [] brackets i need 4 numbers, followed by a whitespace. after that only characters ranging from a to z and – characters are allowed.

so this should be allowed:

[0000] foo-bar

[0000] foo

[0000] foo-bar-foo

etc..

so far i have this:

\[[0-9]{4}\]\s

this matches the [0000] , so it maches the brackets with 4 numbers in it and the whitespace.
i can’t seem to find something that allows charachters after that. i’ve tried putting a single “.” at the end of the expression as this should match any character but this doesnt seem to be working.

\[[0-9]{4}\]\s^[A-Z]+[a-zA-Z]*$

the above isn’t working either..

i need this expression as a Validationexpression for an asp.net custom validator.

any help will be appreciated

This works for your input: http://regexr.com/?30sb7. Unlike Cornstalk’s answer it does not capture anything, and - can indeed be placed later in a range if it’s escaped.
