Extensions.Nodes<T> Method
Returns a collection of the child nodes of every document and element in the source collection.
Namespace: System.Xml.Linq
Assembly: System.Xml.Linq (in System.Xml.Linq.dll)
public static IEnumerable<XNode> Nodes<T>( this IEnumerable<T> source ) where T : XContainer
Type Parameters
- T
The type of the objects in source, constrained to XContainer.
Parameters
- source
- Type: System.Collections.Generic.IEnumerable<T>
An IEnumerable<T> of XNode that contains the source collection.
Return Value
Type: System.Collections.Generic.IEnumerable<XNode>An IEnumerable<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<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).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;
}
}
This example produces the following output:
Text: aaa Element: GrandChild Text: bbb Text: ccc Element: GrandChild Text: ddd
