Use Linq to Xml with Xml namespaces

Question

I have this code :

/*string theXml =
@\"

You can pass an XName with a namespace to Descendants() and Element(). When you pass a string to Descendants(), it is implicitly converted to an XName with no namespace.

To create a XName in a namespace, you create a XNamespace and concatenate it to the element local-name (a string).

XNamespace ns = "http://myvalue.com";
XNamespace nsa = "http://schemas.datacontract.org/2004/07/My.Namespace";

var elements = from data in xmlElements.Descendants( ns + "Result")
                   select new
                              {
                                  TheBool = (bool)data.Element( nsa + "TheBool"),
                                  TheId = (int)data.Element( nsa + "TheId"),
                              };

There is also a shorthand form for creating a XName with a namespace via implicit conversion from string.

var elements = from data in xmlElements.Descendants("{http://myvalue.com}Result")
                   select new
                              {
                                  TheBool = (bool)data.Element("{http://schemas.datacontract.org/2004/07/My.Namespace}TheBool"),
                                  TheId = (int)data.Element("{http://schemas.datacontract.org/2004/07/My.Namespace}TheId"),
                              };

Alternatively, you could query against XElement.Name.LocalName.

var elements = from data in xmlElements.Descendants()
                   where data.Name.LocalName == "Result"
