Use an XPath query like this one:

//link[@type='application/rss+xml']/@href

It'll pull out any RSS feed URL for you. Never parse XML or HTML with regular expressions, ever. XPath is specifically designed to query XML and HTML easy for you. It's available in nearly every technology stack, including .NET.

XML is not regular, and so regex is the incorrect tool to parse it.
