Hi there!

I have an XML File that looks like this:

So there's an Analysis node and several S nodes as siblings. But
there are also CS and DL nodes as siblings of the Analysis node. What
i want is: Capitalize the first character of every @trans that occurs
first in a S node and just print the rest @trans as strings to sdtout ;)

So thats what i wrote:

  But then i recognized that some S nodes can occur in a CS or DL
nodes, so i changed my XPath expression (descendant::*[count
(child::*) = 0]) to tis one: ((ancestor::*)[2])/descendant::*[count
(child::*) = 0] just to test if it works when i take the ancestor
node that comes directly after the Analysis node. It works fine but
the fact is that i get the strings printed 2 or three times. In the
example above it is:

> too a manager describes him
> Perot would be an authoritarian wright and her weakness would be
> too a manager describes him
> Perot would be an authoritarian wright and her weakness would be
> too a manager describes him


So i know why it is printed or processed three times: There a three S
nodes inside the DL node. And here's the point: If i processed the
first S node inside a DL or CS node i don't want to process the
following S nodes in that CS or DL node.

I hope that somebody of you can help me and that somebody of you
understand the problem :)

Thanks in advance
