Obtaining Background-image from stylesheet using C#

Question

Hi everybody.

I am trying to get the value of a "Background-image"-tag in a stylesheet which is used on my web-site. The style-sheets are referenced from the HTML file as follows:

<style media="all" type="text/css">

@import "master.css";

</style>

 
In this file is a "Background-image"-tag which I would very much like to be able to read. Any suggestions?

Best,

Michael
