Parsing of URL fields

[brettz9]

Hi,

I was hoping to get at the URLs within such as the following grabbed from MDN's url page (with or without url()):

background: url('https://mdn.mozillademos.org/files/16761/star.gif') bottom right repeat-x blue;
border-image: url("/media/diamonds.png") 30 fill / 30px / 30px space;
background-image: cross-fade(20% url(first.png), url(second.png));

Any chance you might be inclined to add support for this? I am not interested in using regular expressions, but am hoping for a proper parser that has no false positives or negatives as far as URLs.

Thanks!
