The following example creates an XML tree, and then uses this axis method.


StringBuilder output = new StringBuilder();
XElement xmlTree = new XElement("Root",
    // Attributes are not nodes, so will not be returned by DescendantNodesAndSelf.
    new XAttribute("Att1", "AttributeContent"),
    new XElement("Child",
        new XText("Some text"),
        new XElement("GrandChild", "element content")
    )
);
IEnumerable<XNode> dnas =
    from node in xmlTree.DescendantNodesAndSelf()
    select node;
foreach (XNode node in dnas)
{
    if (node is XElement)
        output.Append((node as XElement).Name + Environment.NewLine);
    else
        output.Append(node + Environment.NewLine);
}
