regex: validate european date format with multiple separators

Question

I want to validate european date formats like \"10.02.2012\" or \"10-02-2012\". Therefore I created the following regex:

/\\d[0-9]{2}(.|-)\\d[0-9]{2}(.|-)\\d         


        

Answer 1

It works correctly after minor modifications :

\d{2}(\.|-)\d{2}(\.|-)\d{4}

1. the "." needs to be escaped.

2. \d is same as [0-9] , no need to repeat it.
