Regex started by space and followed by numbers -


i'm trying evaluate string through regex following rules: string has 5 characters, being first n whitespaces , last 5-n (at least 1) numbers.

(\s*\d{1,5}) works, matches " 12345", outside of rules.

any idea?

try this:

^(?=.{5}$)\s*\d+$

the character limit handled using ahead. rest straightforward.
