How to get specific parent value

[Miroslav Nachev]

   Hi,

   I have the following XML Tree:
   <doc>
      <pages>
         <page id="pg_1">
         </page>
         <page id="pg_2">
            <chapter>
               <article>
                  <article>
                     <article>
                     </article>
                  </article>
                  <article>
                     <article>
                        <article>
                        </article>
                     </article>
                  </article>
               </article>
            </chapter>
         </page>
         <page id="pg_3">
         </page>
      </pages>
   </doc>

   I have some XSL transformation file and when I am in the position
"<article>" I would like to see on which page ID I am. Can some body
help me? How to get the current parent with name "page"? In my case I
don't know on which level of article element I am !!!
   

   Best Regards,
