I came to this question from google. Old one, but none of the answer is discussing about data:image/* urls. Here is what I found on another google result that will only match http or relative urls.

/url\((?!['"]?(?:data):)['"]?([^'"\)]*)['"]?\)/g

I hope this would help other people coming from search engines.
