With .net 3.5, there is a SyndicationFeed that will load in a RSS feed and allow you to run LINQ on it.

Here is an example of the RSS that I am loading:

<rss version="2.0" xmlns:media="http://search.yahoo.com/mrss/"> 
<channel> 
    <title>Title of RSS feed</title> 
    <link>http://www.google.com</link> 
    <description>Details about the feed</description> 
    <pubDate>Mon, 24 Nov 08 21:44:21 -0500</pubDate> 
    <language>en</language> 
    <item> 
    	<title>Article 1</title> 
    	<description><![CDATA[How to use StackOverflow.com]]></description> 
    	<link>http://youtube.com/?v=y6_-cLWwEU0</link> 
    	<media:player url="http://youtube.com/?v=y6_-cLWwEU0" /> 
    	<media:thumbnail url="http://img.youtube.com/vi/y6_-cLWwEU0/default.jpg" width="120" height="90" /> 
    	<media:title>Jared on StackOverflow</media:title> 
    	<media:category label="Tags">tag1, tag2</media:category> 
    	<media:credit>Jared</media:credit> 
    	<enclosure url="http://youtube.com/v/y6_-cLWwEU0.swf" length="233" type="application/x-shockwave-flash"/> 
    </item> 
</channel>

When I loop through the items, I can get back the title and the link through the public properties of SyndicationItem.

I can't seem to figure out how to get the attributes of the enclosure tag, or the values of the media tags. I tried using

SyndicationItem.ElementExtensions.ReadElementExtensions<string>("player", "http://search.yahoo.com/mrss/")

Any help with either of these?
