I have written the code with some help so as to parse the Xml and get the data as 

var reader = new StreamReader(@"C:/Users/Administrator/Downloads/direct.xml")

var xmlDoc = XDocument.Load(reader);

XNamespace atom = "http://www.w3.org/2005/Atom";
XNamespace metadata = "http://schemas.giooglt.com/ado/2007/08/dataservices/metadata";
XNamespace dataservices = "http://schemas.google.com/ado/2007/08/dataservices";

var result = xmlDoc.Root.Elements(atom + "entry")
  .Select(e => new {
      Title = e.Element(atom + "title").Value,
      Id = e.Element(atom + "id").Value,
      Urls = e.Elements(atom + "link")
          .Where(l => l.Element(metadata + "inline") != null)
          .SelectMany(l => l.Element(metadata + "inline")
              .Element(atom + "feed")
              .Elements(atom + "entry")
              .Select(e1 => e1.Element(atom + "content")
                  .Element(metadata + "properties")
                  .Element(dataservices + "Url").Value))
      });

foreach (var item in result)
{
    Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id,item.Urls);
    Debug.WriteLine(item.Urls.GetType());
    foreach(var i in item.Urls){
        Debug.WriteLine("i :"+i);
    }
}

My desired output is -

  M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),http://googlgt.com/en-US/PartnerDetails.aspx? PartnerId=42555&amp;wt.mc_id=66ttet
  M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),http://pinpoint.microsoft.com/en-US/RFI.aspx?partnerId=4295719419&amp;wt.mc_id=54545
  vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),http://googlgt.com/en-US/PartnerDetails.aspx?PartnerId=42555&amp;wt.mc_id=66ttet
  vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),http: //pinpoint.microsoft.com/en-US/RFI.aspx?partnerId=4295719419&amp;wt.m

But the output I am getting from the above piece of code is : 

 M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]      
 M55p; Co,http://pinpoint.microsoft.com/en-US/syndicate/Partners('4555'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String] 
 vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]
 vfere,http://pinpoint.microsoft.com/en-US/syndicate/Partners('45'),System.Linq.Enumerable+<SelectManyIterator>d__14`2[System.Xml.Linq.XElement,System.String]

I am getting the output as specified above and I am not quite sure why am I getting the above output. I desire to get the result for each 'Url' as is specified in the desired output. been fighting for a while to get the desired result.

Any help is appreciated. Novice programmer, new to C# not sure how to get the output. Is this because of the wrong XML format?

Solution

Your code is trying to call ToString() on a Linq expression which is why you're seeing that System.Linq.Enumerable+ gobbledygook.

You need to enumerate the Urls:

foreach (var item in result)
{
    var i = 0;
    foreach (var url in item.Urls)
    {
        Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id, url);
        Debug.WriteLine(url.GetType());
        Debug.WriteLine("i : " + i++);
    }
}

or a more succinct way to write this:

result.ToList().ForEach(item =>
{
    var i = 0;
    foreach (var url in item.Urls)
    {
        Debug.WriteLine("{0}, {1}, {2}", item.Title, item.Id, url);
        Debug.WriteLine(url.GetType());
        Debug.WriteLine("i : " + i++);
    }
});
