XContainer.DescendantNodes Method

Returns a collection of the descendant nodes for this document or element, in document order.

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

public IEnumerable<XNode> DescendantNodes()

Return Value

Type: System.Collections.Generic.IEnumerable<XNode>
An IEnumerable<T> of XNode containing the descendant nodes of the XContainer, in document order.

Note that attributes are not considered to be nodes in LINQ to XML, so they will not be part of the collection that is returned by this method.

This method uses deferred execution.

The following example creates an XML tree, and then iterates through the DescendantNodes axis.

XElement xmlTree = new XElement("Root",
    // Attributes are not nodes, so will not be returned by DescendantNodes.
    new XAttribute("Att1", "AttributeContent"),
    new XElement("Child",
        new XElement("GrandChild", "element content")
    )
);
IEnumerable<XNode> dnas =
    from node in xmlTree.DescendantNodes()
    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:

Child
GrandChild
element content
