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. . . . . . . . . . .
