Depending on your FO implementation you may not need to generate the PDF 
 but you will have to process the FOs involved.

With Antenna House XSL Formatter, using it's Java or .NET API, you can 
process FO input and get back the number of pages produced, without also 
generating any actual output. This makes it possible to do what you 
might call "one and a half pass" processes when you need to know the 
page count for things.  You can integrate this with your XSLT by writing 
an XSLT extension function (e.g., write a Saxon extension that uses the 
XSL Formatter Java API).

I believe RenderX XEP has similar capabilities but I've not tried to do 
it with XEP.

As mentioned, worst case is you generate PDF and use a tool like iText 
or PDFBox or another PDF library to get the page count and then do a 
second pass.

Cheers,

Eliot
