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

Dim output As New StringBuilder
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
    output.Append(el.Name)
    output.Append(Environment.NewLine)
Next


OutputTextBlock.Text = output.ToString()
