Parsing result from WCF WebHttp Service - wcf

Question

I have a very simple WCF service running which returns the following (from a basic new project) xml:
<ArrayOfSampleItem xmlns="http://schemas.datacontract.org/2004/07/WcfRestService1" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<SampleItem>
<Id>1</Id>
<StringValue>Hello</StringValue>
</SampleItem>
</ArrayOfSampleItem>
I am then consuming this in a Windows Phone 7 app. The result is coming back fine however I'm having problems parsing the xml. This is the code I am using on the callback after completion of the request:
XDocument xmlDoc = XDocument.Parse(e.Result);
itemsFetched.ItemsSource = from item in xmlDoc.Descendants("SampleItem")
select new Product()
{
Id = item.Element("Id").Value,
StringValue = item.Element("StringValue").Value
};
The collection is not populated with this, when I try adding the namespace:
XNamespace web = "http://schemas.datacontract.org/2004/07/WcfRestService1";
XDocument xmlDoc = XDocument.Parse(e.Result);
itemsFetched.ItemsSource = from item in xmlDoc.Descendants(web + "SampleItem")
The item is found but I get a null exception when it attempts to get the Id value.
Any help would be much appreciated.

Well the xmlns="..." puts the elements and all its descendants in the namespace so you need to use your XNamespace object web anywhere where you access elements:
XDocument xmlDoc = XDocument.Parse(e.Result);
XNamespace web = "http://schemas.datacontract.org/2004/07/WcfRestService1";
itemsFetched.ItemsSource = from item in xmlDoc.Descendants(web + "SampleItem")
select new Product()
{
Id = item.Element(web + "Id").Value,
StringValue = item.Element(web + "StringValue").Value
};
