This is relatively easy, but you have to leverage non-FO mechanisms
in XEP. Essentially, the trick is to intercept pages as they go from
the formatter to the output generator, and skip the last one. XEP Client
edition or better is required - you will need either an XML output
(area tree) producer, or API access.
Using command-line interfaces, the procedure would look like this:
1. Produce the layout in XML from your FO/XML+XSL:
xep -fo input.fo -at tmp.xml
2. Strip the last <page> element from tmp.xml. e.g. by applying
an identity XSL transformation with a disabling template for the
3. Feed the result back, by invoking com.renderx.xep.Printer class:
java -cp [...] com.renderx.xep.Printer tmp_filtered.xml
If you have Server or Developer edition of XEP, you can do this
directly in the API, without saving files to disk. ConcatFormatter
sample from Java samples may be useful to figure out how to
plug a custom filter to XEP output.
