 I'm using Saxon 6.5 and the group and item extensions to make this process reasonable. I've got the headings seeming to work properly up to 3 levels with see and see also support. Now I'm trying to gather up the page numbers with their markup and output them as a single statement once all the page numbers are gathered. The process I wrote myself into has me collecting the page numbers in a variable that I can assign to with another saxon function. This was the template I had written: <xsl:template name="page-sequence">
<xsl:param name="NumberPage" select="false()" /><xsl:if test="$NumberPage"> <xsl:choose> <xsl:when test="$pageNumber=''"> <saxon:assign name="pageNumber"> <fo:leader leader-pattern="dots" leader-length="1in" /> <fo:basic-link internal-destination="{generate-id()}"> <fo:page-number-citation ref-id="{generate-id()}" /> </fo:basic-link> </saxon:assign> </xsl:when> <xsl:otherwise> <!-- similar stuff here for continuation --> </xsl:otherwise> </xsl:choose> </xsl:if> </xsl:template> As you see I'm assigning the <fo> markup to the variable and in the otherwise, I was adding additional page numbers with a comma separator. What I'm at a loss for is the proper test in the <choice> to see if there is content in $pageNumber. First what is the proper way to reset the variable to be empty and hopefully no nodes in the node-set? Does a simple <saxon:assign name="pageNumber"/> do it? What is the best test to detect content in $pageNumber? I tried count() but it always returns 1, and the test for the empty string is not working either. thanks ..dan --------------------------------------------------------------------------- Danny Vint Specializing in Panoramic Images of California and the West http://www.dvint.com voice: 510-522-4703
