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

public:
generic <typename T>
 where T : System::Xml::Linq::XContainer[System::Runtime::CompilerServices::Extension]
 static System::Collections::Generic::IEnumerable<System::Xml::Linq::XNode ^> ^ Nodes(System::Collections::Generic::IEnumerable<T> ^ source);

public static System.Collections.Generic.IEnumerable<System.Xml.Linq.XNode> Nodes<T>(this System.Collections.Generic.IEnumerable<T> source) where T : System.Xml.Linq.XContainer;

public static System.Collections.Generic.IEnumerable<System.Xml.Linq.XNode> Nodes<T>(this System.Collections.Generic.IEnumerable<T?> source) where T : System.Xml.Linq.XContainer;

static member Nodes : seq<'T (requires 'T :> System.Xml.Linq.XContainer)> -> seq<System.Xml.Linq.XNode> (requires 'T :> System.Xml.Linq.XContainer)

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

<Extension()>
Public Iterator Function Nodes(Of T As XContainer) (source As IEnumerable(Of T)) As IEnumerable(Of XNode)

Type Parameters

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

Parameters

Returns

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(  
    @"<Root><Child>aaa<GrandChild>Text</GrandChild>bbb</Child>" +  
    @"<Child>ccc<GrandChild>Text</GrandChild>ddd</Child></Root>");  
IEnumerable<XNode> 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 = _  
    <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

Remarks

This method uses deferred execution.
