You are clearly having a bad day, as am I, so let's not quibble about the
well-formedness of your xml...

I assume you meant that the structure is like this

<Assembly>
   <Station name="Station1">
      <WI order="1" title="doc1">
         <Boards>
            <Board sn="111"/>
            <Board sn="112"/>
         </Boards>
      </WI>
      <!-- More WI elements -->
   </Station>
   <!-- More Station Elements -->
</Assembly>

If you have used 'select = "./WI/Boards/Board"' then each of the nodes
selected is a Board

'..' is the shorthand for referring to the parent node.  In this context
'../@order' is asking for the order attribute of the parent of a Board i.e
the order attribute of a Boards element.  You should expect 'a blank' in
this case.  What you appear to require is the order attribute of the
grandparent of the Board so you should use '../../@order'

Cheers,
