AW: AW: document() and position()

Jeni,

thank you for the hint. It's the XSLT processor.
We have two XSLT processors in use. The first one
is the xalan (this is the one I have the problems).
The output is:

News item 1[2.xml] News item 1[4.xml]

The second one is the xt. I've tried the same
files on the xt and the output is:

News item 1[2.xml] News item 2[4.xml]


Is one of the XSLT processors *the best*? We've
changed from xt to xalan because of the
support. But as it seems it's not the best
choice.

For this problem I have to do a workaround,
because there is no time to change the
XSLT processor. But for the future I
will know.

Thank you very much for your support.

sunny greetings from the lake
