kennethk++ is right. I'd just like to post a word of warning concerning this part of your regex:[[:alnum:]\.-:]+
Firstly, you don't need to escape the dot in a character class (but there's nothing stopping you from doing so...). More importantly, the sequence\.-:
(with or without the backslash) in a character class means "any character between '.' (dot) and ':' (colon) (inclusive)".
As it happens, the only things in the ASCII (or UTF, or whatever) table between these two characters are the forward slash and the digits 0-9 (the latter being included, of course, in [:alnum:]).
The point is, that if you want to put a literal hyphen in a character class, you should generally put it at the very beginning or the very end, or else escape it with a backslash.
