XElement.DescendantNodesAndSelf Method

Definition

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

public:
 System::Collections::Generic::IEnumerable<System::Xml::Linq::XNode ^> ^ DescendantNodesAndSelf();
public System.Collections.Generic.IEnumerable<System.Xml.Linq.XNode> DescendantNodesAndSelf ();
member this.DescendantNodesAndSelf : unit -> seq<System.Xml.Linq.XNode>
Public Function DescendantNodesAndSelf () As IEnumerable(Of XNode)

Returns

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

Examples

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

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);
}
Dim xmlTree As XElement = _
    <Root Att1="AttributeContent">
        <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:

Root
Child
Some text
GrandChild
element content
