"Uncle"

Is there someone who knows how to teste if a node is an "uncle" of another?
Example:

<wine grape="Chardonnay">
    <winery>Lindeman's</winery>
    <product>Bin 65</product>
    <year>1998</year>
    <desc>Youthful, with a cascade of spicy fig.</desc>
    <prices>
      <list>6.99</list>
      <discounted>5.99</discounted>
      <case>71.50</case>
    </prices>
</wine>

I wanna test if desc is uncle of list.

Thanks
