If you want the id of the nearest po ancestor that is 
ancestor::po[1]/@id

but that would be something else, for example on  <someelement/> would
you want to discount  <po id="3">, because it's your parent.

anyway the nearest po answer that isn't your parent is the nearest
ancestor of your parent, which is
../ancestor::po[1]/@id
