XContainer.DescendantNodes Method

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

Namespace:  System.Xml.Linq
Assemblies:   System.Xml.Linq (in System.Xml.Linq.dll)
  System.Xml.XDocument (in System.Xml.XDocument.dll)

Public Function DescendantNodes As IEnumerable(Of XNode)

Return Value

Type: System.Collections.Generic.IEnumerable(Of XNode)
An IEnumerable(Of 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.

' Attributes are not nodes, so will not be returned by DescendantNodes.
Dim xmlTree As XElement = _ 
    <Root Att1="AttributeContent">
            <GrandChild>element content</GrandChild>

Dim dnas = From node In xmlTree.DescendantNodes _
           Select node

For Each node In dnas
    If TypeOf node Is XElement Then
        Console.WriteLine(DirectCast(node, XElement).Name)
    End If

This example produces the following output:
