So, I was wondering if it was possible to do a foreach for the number
of pages in the document, minus a number provided in the xml.
Basically, I have a flow that I want to end on the last page, rather
than start on the first page. If I could add page breaks for how many
pages the document is minus how many pages the flow is going to take
up, I could easily do this. It does, however, seem like something that
could easily be impossible, since the for-each could impact the number
of pages, and what would the processor do then?
In the XSL-FO specification there is no feedback from the XSL-FO
processor back to the transformation you are using to create your
XSL-FO instance (typically XSLT but it doesn't have to
be). Therefore, you can never know at transformation time how many
pages the formatting will take.
You can consider what vendors may offer with their specific
products. For example, the RenderX tool has an intermediate format
that you can massage between the formatting and the rendering.
Another possibility is to inspect the PDF you create and do a second
pass with your input as I do with the "back of the book index"
facility I posted for XSLT 1.0 users as a free developer resource on
my web site. Using a tool like iText you can count the number of
pages in the PDF file and then re-run your transformation with that knowledge.
I hope this helps.
