I used [Mike Brind's Sitemap code][1], with a small change.
You need to add the XNamespace to every XElement, otherwise Google spits the dummy.
Here's my version:
public ContentResult Index()
{
XNamespace ns = "http://www.sitemaps.org/schemas/sitemap/0.9";
const string url = "http://www.website.com/controller/action/{0}";
var items = _db.DataAccessHere();
var sitemap = new XDocument(
new XDeclaration("1.0", "utf-8", "yes"),
new XElement(ns + "urlset",
from i in items
select
//Add ns to every element.
new XElement(ns + "url",
new XElement(ns + "loc", string.Format(url, i.ItemID)),
new XElement(ns + "lastmod", String.Format("{0:yyyy-MM-dd}", i.DateAddedUTC)),
new XElement(ns + "changefreq", "monthly"),
new XElement(ns + "priority", "0.5")
)
)
);
return Content(sitemap.ToString(), "text/xml");
}
