Nodes Method

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 Function Nodes As IEnumerable(Of XNode)

Return Value

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

An IEnumerable(Of 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.


                Dim xmlTree As XElement = _ 
        <Root>
            <Child1>1</Child1>
            <Child2>2</Child2>
            <!--a comment-->
            <Child3>3</Child3>
            <Child4>4</Child4>mixed content<Child5>5</Child5>
            </Root>

Dim nodes = From nd In xmlTree.Nodes() _
            Select nd

For Each node In nodes
    Console.WriteLine(node)
Next

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.


                Dim xmlTree As XDocument = _ 
    <?xml version="1.0" encoding="utf-8"?>
    <!--a comment-->
    <?xml-stylesheet type='text/xsl' href='hello.xsl'?>
    <Root Att="attContent">
        <Child1><![CDATA[CDATA content]]></Child1>
        <Child2>Text content</Child2>
    </Root>

' Note that XNode uses XmlNodeType, which is in the System.Xml namespace
For Each node In xmlTree.Nodes
    Console.WriteLine(node.NodeType.ToString())
    If node.NodeType = XmlNodeType.Element Then
        For Each att In DirectCast(node, XElement).Attributes
            Console.WriteLine(att.NodeType.ToString())
        Next
        For Each node2 In DirectCast (node, XElement).Nodes()
            Console.WriteLine(node2.NodeType.ToString())
            If node2.NodeType = XmlNodeType.Element Then
                For Each node3 In DirectCast (node2, XElement).Nodes
                    Console.WriteLine(node3.NodeType.ToString())
                Next
            End If
        Next
    End If
Next
