I'm creating pdf with xsl:fo.
I have a loop that is creating thousands of rows. On page 4, for example, I
want something more written in the cells.
How do I check for page numbers?

Something like:
<xsl:choose>
  <xsl:when test="pagenumber=4"> <!-- How do I test this???????

This cannot be tested.


You are missing the issue that XSLT happens and ends long before XSL-FO is interpreted. There is no feedback loop and your transformation process has no knowledge of the results of the anticipated formatted process.

The way XSL-FO works is you supply contingencies for those kinds of situations the formatter finds itself in where having a contingency for a testable activity can be chosen instead of the default process.

The only contingency you could supply for being on page 4 is a sequence of page geometries that might trigger different static content for that page ... but you cannot, say, conditionally add content to the middle of a stream of blocks being formatted.

Perhaps you can describe what you need as your result, because you have gotten off on a tangent asking about an approach that doesn't exist.

I hope this helps.
