Thanks Georg for the quick response!
I must admit I'm not too familiar with java.xml.* package - just able to
render out a PDF and that's it. So I'm having difficulty following your
example.
Assuming I have a template.xsl file and a data.xml file, I assumed I would
have to simulate/emulate using FOP to transform the data.xml via the
template.xsl into a PDF (or really a tree in memory).
In your example I follow that the xsl is passed in...but I don't see
how/where the data.xml would come into it.
If this is not the right forum, any ideas where/who I should try?
Thanks again!
