如何从rss文件中获取选定的项目？

Question

Example code:

<rss version="2.0">
<channel>
  <item>
    <title>Title /title>
    <link>Link</link>
    <description>Desc</description>
  </item>
  <item>
    <title>Title</title>
    <link>Link</link>
    <description>Desc</description>   
  </item>
</channel>
</rss>

I get data from link:

XElement rss = XElement.Load("http://examplelink.com/file.rss");

and i want to save it but without any other elements, only title and link:

rss.Save(@"C:\doc.txt");

How to do that?
