'Declaration
<ExtensionAttribute> _
Public Shared Function Nodes(Of T As XContainer) ( _
	source As IEnumerable(Of T) _
) As IEnumerable(Of XNode)

Type Parameters

T

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

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.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IEnumerable(Of T). When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).

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
