How to display nested XML-elements in report with XML datasource in Active Reports 6

Question

I have following xml structure and I would like them to display in the report.

{...}
<order id="121">
  <item>
     <fees>
        <fee id="23">
                {...}
         </fee>
     </fees>
     <discounts>
        <discount id="1">
                {...}
         </discount>
     </discounts>
  </item>
 <item>
    ....
</item>
</order>
<order id="142">
{...}
</order>

My problem is that the children of the and element are not displayed in the report whatever xpath expression i use. I even tried to use a subreport but it still does not display! Does anybody have an idea how this can be achieved in active reports! Any help would be greatly appreciated!
