        <Child>Some text<GrandChild>element content</GrandChild>
        </Child>
    </Root>

Dim dnas As IEnumerable(Of XNode) = _
    From node In xmlTree.DescendantNodesAndSelf() _
    Select node


For Each node In dnas
    If TypeOf node Is XElement Then
        Console.WriteLine(DirectCast(node, XElement).Name)
    Else
        Console.WriteLine(node)
    End If
Next

This example produces the following output:
