This:

(.*?)(url\()(?!["']?http|["']?/)(["']?)(?<Url>.*?)["']?\)(.*?)

seems to work for all of the following lines:

background-image: url(../images/default/shadow-c.png);
background-image: url('../images/icons/file-xslx.gif') !important;
background-image: url("../images/icons/file-xslx.gif") !important;
background-image: url('../images/icons/file-xslx.gif") !important;
background-image: url(../images/icons/file-xslx.gif") !important;
background-image: url("../images/icons/file-xslx.gif) !important;
background-image: url(/images/icons/file-xslx.gif) !important;
background-image: url('/images/icons/file-xslx.gif') !important;
background-image: url("/images/icons/file-xslx.gif") !important;
background-image: url('http://example.com/images/icons/file-xslx.gif')
!important;
background-image: url(http://example.com/images/icons/file-xslx.gif)
!important;

The first 3 are properly formatted relative URLs, and match the pattern.
The next 3 are badly-fomatted  relative URLs, which match the pattern
anyway (I could change that, but it's probably best this way)
The last 5 are absolute URLs and do not match the pattern.
