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

public static IEnumerable<XNode> DescendantNodesAndSelf(
	this IEnumerable<XElement> source
)

Parameters

source
Type: System.Collections.Generic.IEnumerable<XElement>

An IEnumerable<T> of XElement that contains the source collection.

Return Value

Type: System.Collections.Generic.IEnumerable<XNode>
An IEnumerable<T> of XNode that contains every element in the source collection, and the descendant nodes of every 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<XElement>. 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).

Although Visual Basic has an integrated XML axis for descendant elements, there is no integrated axis for descendant nodes, so Visual Basic users must use this axis method explicitly.

This method uses deferred execution.
