regular expressions

Ok, i am trying to change links using a regular expression. I can change all but relative links. What i am looking to do is have it ignore any link that starts with [url]http://.[/url]

[CODE]
“‘(@imports|url(|href|src)=(“|’|)(.*?)(“|’|)s'”
————————————^^
[/CODE]

Where the arrow marks is where i think it should be. I was trying something like (^{^[url]http://[/url])} and [^{^([url]http://[/url])]} but neither work. Does anyone know how i can do it?

PS. I only want it to work on relative links.

Thanks.
