XContainer.Nodes Method

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

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

public IEnumerable<XNode> Nodes()

Return Value

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

Note that the content does not include attributes. In LINQ to XML, attributes are not considered to be nodes of the tree. They are name/value pairs associated with an element.

This method uses deferred execution.

The following example creates an XML tree with a variety of types of nodes. It then queries this axis method to enumerate and print the nodes.

XElement xmlTree = new XElement("Root",
    new XElement("Child1", 1),
    new XElement("Child2", 2),
    new XComment("a comment"),
    new XElement("Child3", 3),
    new XElement("Child4", 4),
    new XText("mixed content"),
    new XElement("Child5", 5)
);
IEnumerable<XNode> nodes =
    from nd in xmlTree.Nodes()
    select nd;
foreach (XNode node in nodes)
    Console.WriteLine(node);

This example produces the following output:

<Child1>1</Child1>
<Child2>2</Child2>
<!--a comment-->
<Child3>3</Child3>
<Child4>4</Child4>
mixed content
<Child5>5</Child5>

The following example creates an XML tree that contains a variety of types of nodes. It then enumerates through portions of the tree, printing the node types.

XDocument xmlTree = new XDocument(
    new XComment("a comment"),
    new XProcessingInstruction("xml-stylesheet", "type=\"text/xsl\" href=\"hello.xsl\""),
    new XElement("Root",
        new XAttribute("Att", "attContent"),
        new XElement("Child1",
            new XCData("CDATA content")
        ),
        new XElement("Child2",
            new XText("Text content")
        )
    )
);

foreach (XNode node in xmlTree.Nodes())
{
    Console.WriteLine(node.NodeType);
    if (node.NodeType == XmlNodeType.Element)
    {
        foreach (XAttribute att in ((XElement)node).Attributes())
            Console.WriteLine(att.NodeType);
        foreach (XNode node2 in ((XElement)node).Nodes())
        {
            Console.WriteLine(node2.NodeType);
            if (node2.NodeType == XmlNodeType.Element)
                foreach (XNode node3 in ((XElement)node2).Nodes())
                    Console.WriteLine(node3.NodeType);
        }
    }
}

This example produces the following output:
