[xep-support] Creating a Table of Contents from an HTML file being transformed using XSL to FO

[Kenneth Aitken]

Hi Werner,

Our problem is that we have already adapted an Antenna House stylesheet and it works fine for us except for a couple of problems. Creating a 3-level table of contents is the most urgent issue and I do not have time to create a completely new XSLT stylesheet from scratch.
We created a TOC with h1 and h2 from XHTML by using the<div> tag to nest h2. But going from h2 to h3 seems to be much more difficult, and as yet, we have not succeeded. Below is the code for creating a TOC, with h1 and h2 (the block after each h1 is contained in a <div class = "x"></div> block). 

Any ideas?

Greetings,

Kenneth

  <!--=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-
       TOC
  =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-->  
  
<xsl:template match="html:h1" mode="toc">
  <fo:block text-align-last="justify" font-size="14pt" space-before="8mm" space-after="4mm">
    <fo:basic-link internal-destination="{generate-id(.)}">

   <xsl:apply-templates/>
    </fo:basic-link>
    <xsl:text> </xsl:text>
    <fo:leader leader-length.minimum="12pt" leader-length.optimum="40pt"
               leader-length.maximum="100%" leader-pattern="space"/>
    <xsl:text> </xsl:text>
    <fo:page-number-citation ref-id="{generate-id(.)}"/>
  </fo:block>
<!-- the following selects *all* <h2> elements that are on the same level as the <h1> element -->
  <xsl:apply-templates select="../html:h2" mode="toc"/>
</xsl:template>
  
<xsl:template match="html:h2" mode="toc">
  <fo:block start-indent="10mm" text-align-last="justify" font-size="10pt">
    <fo:basic-link internal-destination="{generate-id(.)}">
      <xsl:apply-templates/>
    </fo:basic-link>
    <xsl:text> </xsl:text>
    <fo:leader leader-length.minimum="12pt" leader-length.optimum="40pt"
               leader-length.maximum="100%" leader-pattern="dots"/>
    <xsl:text> </xsl:text>
    <fo:page-number-citation ref-id="{generate-id(.)}"/>
  </fo:block>
</xsl:template>
