If the site uses feedburner you can't take original URL Address
you should use this code

var x = (from it in XD.Descendants("item")
orderby DateTime.Parse(it.Element("pubDate").Value) ascending
where DateTime.Parse(it.Element("pubDate").Value) > prmLastEntry
select it.Elements()).ToArray();
// and

foreach (var itemx in x)
{
foreach (var itemsub in itemx)
{
if (itemsub.Name == "{http://rssnamespace.org/feedburner/ext/1.0}origLink")
{
string OriginalLink = itemsub.Value;
}
}
}
