I'm still working on my Index. Now I'm trying to gather the index terms up
and group them and then generate the page numbers.
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
