Hi

How do I backtrack the originating node of a descendant node, until I reach the root element? Hence if my given structure is of the form:

<Top>
   <SubConcepts>
         <SubConcept id="990" name="Level1">
               <Child ref="567">Child1</Child>
               <Value ref="456">hasFeature BrokenBolt</Value>
         </SubConcept>
         <SubConcept id="456" name="BrokenBolt">
               <Child ref="345">Child2</Child>
               <Value ref="123">hasProperty NextTime</Value>
         </SubConcept>
   </SubConcepts>
</Top>

I find my result in the <Value ref="123"> node with the contained value 'Time'. I can find the parent of this with the name() function 'BrokenBolt' as the control is at the <SubConcept id="456"> level. I'd like to iterate backwards using the 'id'='ref' match so I get a result of the order:


Match found: Next
Parent: BrokenBolt
         Parent: Level1
         Parent: SubConcepts


Thanks
Rahil
