Public Function AncestorsAndSelf As IEnumerable(Of XElement)

Return Value

Type: System.Collections.Generic.IEnumerable(Of XElement)

An IEnumerable(Of T) of XElement of elements that contain this element, and the ancestors of this element.

The elements in the returned collection are in reverse document order.

This method uses deferred execution.

The following example creates an XML tree. It then finds the GrandChild element, and then prints the ancestors of it.


                Dim xmlTree As XElement = _ 
    <Root>
        <Child>
            <GrandChild>element content</GrandChild>
        </Child>
    </Root>

Dim GC As XElement = xmlTree.<Child>.<GrandChild>(0)

Dim aas As IEnumerable(Of XElement) = _
    From el In GC.AncestorsAndSelf() _
    Select el

For Each el In aas
    Console.WriteLine(el.Name)
Next

This example produces the following output:


                GrandChild
Child
Root
