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

<ExtensionAttribute>
Public Shared Function Nodes(Of T As XContainer) (
	source As IEnumerable(Of T)
) As IEnumerable(Of XNode)

Parameters

source
Type: System.Collections.Generic.IEnumerable(Of T)

An IEnumerable(Of T) of XNode that contains the source collection.

Return Value

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

An IEnumerable(Of T) of XNode of the child nodes of every document and element in the source collection.

Type Parameters

T

The type of the objects in source, constrained to XContainer.

This method uses deferred execution.

The following example retrieves all of the child nodes for every node in a collection of elements with the name of Child.


                Dim xmlTree As XElement = _
    <Root>
        <Child>aaa<GrandChild>Text</GrandChild>bbb</Child>
        <Child>ccc<GrandChild>Text</GrandChild>ddd</Child>
    </Root>

Dim nodes = xmlTree.<Child>.Nodes()

' Note that XNode uses XmlNodeType, which is in the System.Xml namespace.
For Each node As XNode In nodes
    Select Case node.NodeType
        Case XmlNodeType.Element
            Console.WriteLine("Element: {0}", DirectCast(node, XElement).Name)
        Case XmlNodeType.Text
            Console.WriteLine("Text: {0}", DirectCast(node, XText).Value)
    End Select
Next

This example produces the following output:

Text: aaa
Element: GrandChild
Text: bbb
Text: ccc
Element: GrandChild
Text: ddd
