Returns a collection of the child nodes of every document and element in the source collection.

public:
generic 
 where T : System::Xml::Linq::XContainer[System::Runtime::CompilerServices::Extension]
 static System::Collections::Generic::IEnumerable ^ Nodes(System::Collections::Generic::IEnumerable ^ source);
public static System.Collections.Generic.IEnumerable Nodes(this System.Collections.Generic.IEnumerable source) where T : System.Xml.Linq.XContainer;
public static System.Collections.Generic.IEnumerable Nodes(this System.Collections.Generic.IEnumerable source) where T : System.Xml.Linq.XContainer;
static member Nodes : seq<'T (requires 'T :> System.Xml.Linq.XContainer)> -> seq (requires 'T :> System.Xml.Linq.XContainer)

Public Function Nodes(Of T As XContainer) (source As IEnumerable(Of T)) As IEnumerable(Of XNode)

Public Iterator 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
IEnumerable

An IEnumerable of XNode that contains the source collection.

Returns

IEnumerable<XNode>

An IEnumerable of XNode of the child nodes of every document and element in the source collection.

Examples

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

XElement xmlTree = XElement.Parse(
    @"aaaTextbbb" +
    @"cccTextddd");
IEnumerable nodes = xmlTree.Elements("Child").Nodes();

foreach (XNode node in nodes)
{
    switch (node.NodeType)
    {
        case XmlNodeType.Element:
            Console.WriteLine("Element: {0}", ((XElement)node).Name);
            break;
        case XmlNodeType.Text:
            Console.WriteLine("Text: {0}", ((XText)node).Value);
            break;
    }
}

Dim xmlTree As XElement = _
    
        aaaTextbbb
        cccTextddd
    

Dim nodes = xmlTree..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

This method uses deferred execution.
