XElement.DescendantNodesAndSelf Method

Returns a collection of nodes that contain this element, and all descendant nodes of this element, in document order.

Namespace:  System.Xml.Linq
Assembly:  System.Xml.Linq (in System.Xml.Linq.dll)

public IEnumerable<XNode> DescendantNodesAndSelf()

Return Value

Type: System.Collections.Generic.IEnumerable<XNode>
An IEnumerable<T> of XNode that contain this element, and all descendant nodes of this element, in document order.

This method uses deferred execution.

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

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)
        Console.WriteLine((node as XElement).Name);
    else
        Console.WriteLine(node);
}

This example produces the following output:

Root
Child
Some text
GrandChild
element content
