Linq to Xml: Generate Google Sitemap with sitemap-protocol

In this example I will generate a XML site-map that complies with the sitemap-protocol XML schema.

//create datasource

List blogPosts = new List{
 "http://blog.newguid.net/mypost1.aspx",
 "http://blog.newguid.net/mypost_about_Net.aspx",
 "http://blog.newguid.net/morePosts.aspx",
 "http://blog.newguid.net/andEvenMorePosts.aspx"
};

//Create namespace for sitemap-protocol

XNamespace xmlNS = "http://www.sitemaps.org/schemas/sitemap/0.9";
XDocument xmlDoc =
 new XDocument(
  new XDeclaration("1.0", "UTF-8", null),
  new XElement(xmlNS + "urlset",
   from blogPostUrl in blogPosts
   select
    new XElement(xmlNS + "url",
    new XElement(xmlNS + "loc", blogPostUrl))
    ));

//Show output

Response.Write(xmlDoc);

This example will give the following output:

&lt;urlset xmlns=&quot;<a href="http://www.sitemaps.org/schemas/sitemap/0.9">http://www.sitemaps.org/schemas/sitemap/0.9</a>"&gt;
  
    http://blog.newguid.net/mypost1.aspx
  
  
    http://blog.newguid.net/mypost_about_Net.aspx
  
  
    http://blog.newguid.net/morePosts.aspx
  
  
    http://blog.newguid.net/andEvenMorePosts.aspx
  

To keep the example as simple as possible I only use the LOC element of the URL node. In the real world you can implement the lastmod, changefreq and priority node.
