[Qexo-general] Parent Navigation

[Sascha Opletal]

I am very grateful for the help this list provides, especially Per Bothner.

The (hopefully) last Problem i have with Qexo is the parent navigation.

The Data is:

<a>
<b c="1" d="3">1</b>
...
</a>

Now i want to go over the c-Values (there are more than one b-element in 
real data).

I use this:

for $a in doc("data2.xml")/a/b/@c

return
<result>
{$a}
{$a/../@d} 
</result>

Besides attaching the /a/b/@c, i also want to attach the relevant 
attribute @d in context.
The line
{$a/../@d} 

Gives the following error:

java.lang.ArrayIndexOutOfBoundsException: 2146304153

How do i access the other attribute which is parallel to the first, 
without changing the for-loop?

Thank you for your help!
