/any_string/any_string/any_number
with this regular expression:
/(\w+).(\w+).(\d+)/
It works, but I need this url:
/specific_string/any_string/any_string/any_number
And I don't know how to get it.
/(specific_string).(\w+).(\w+).(\d+)/
Though note that the .s in your regular expression technically match any character and
not just the /
/(specific_string)\/(\w+)\/(\w+)\/(\d+)/
This will have it match only slashes.
