Examples
The following example creates an XML tree, and then uses this axis method.
C#
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); }
Visual Basic
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
