Navigating XElement

The XMl looks like this:

I first create a navigator with an XPath expression to get the nodes set I want to work with:

XElement root = XElement.Load("data.xml");
var answers = root.CreateNavigator().Select("/Category/Subject/Question/Answer");

Then I loop through each answer...

while (answers.MoveNext())
{

Here I convert the underlying object to an Element to get the values:

var details = answers.Current.UnderlyingObject as XElement;

Now I can access the elements I want:

var val = details.Element("Description").Value;

}
