An IEnumerable<T> of XElement of elements that contain this element, and all descendant elements of this element, in document order.

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

XElement xmlTree = new XElement("Root",
    new XAttribute("Att1", "AttributeContent"),
    new XElement("Child",
        new XText("Some text"),
        new XElement("GrandChild", "element content")
    )
);
IEnumerable<XElement> das =
    from el in xmlTree.DescendantsAndSelf()
    select el;
foreach (XElement el in das)
    Console.WriteLine(el.Name);

This example produces the following output:

Root
Child
GrandChild
