Re: xpath - check for no content

I have to transform this into xsl:fo !
so, i do really NEED the additional break here!
background is- i am tranforming a Lotus Notes XML Export into a PDF
Dokument.
Some linbreaks and Paragraphs don't "get through" my templates at the
moment.
I am trying to figure out what's wrong or try to find a workaround, so that
the output looks like the Notes document.

I will try to see if your hints get me any further.
Thanks,
Sascha
