[Exist-open] XPath gives wrong result

[Evert H. <eve...@pi...>]

Hi,

I have found a case where XPath evaluates incorrectly. I have tested it 
with Xalan too and Xalan does it correctly.

The xml is the following:
<section id="a">
  <section id="b">
    <section id="c"/>
  </section>
</section>

I am trying to select "b" and all its parents, thus "a" and "b".

Here is the XPath expression that I used:
//section[descendant-or-self::section[@id='b']]

eXist only returns "b".

Xalan returns "a" and "b".

Do you know of another way in which I can select a node with all its 
parents? In Xalan I can do it in two steps: I can first select the node 
via its ID and then I can use this node as a context node for the next 
XPath expression which will then just get the ancestors. I haven't found 
a way to specify a context node in eXist.

Thanks in advance,
Evert
