Index with Pagenumbers

alleycat · March 15th, 2006, 10:53 AM

I have the following XHTML:

-----------input.xhtml---------
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
  <title>The Input file</title>
</head>
<body>
  <h1 id="1.">1. Intro</h1>
  <p>some text</p>
  <h1 id="2.">2. Content</h1>
  <p>some text</p>
  ... and so on ...
</body>
</html>
-------------------------

Now I would like to generate an index and after the index there should be the content.

The index should look like:
1. Intro .............................. Page 1
2. Content ............................ Page 4
. . . and so on . . .

This is the job of mkindex.xsl:

-----------mkindex.xsl---------
<?xml version="1.0" encoding="iso-8859-1"?>

<xsl:stylesheet
  version="1.1"
  xmlns="http://www.w3.org/1999/xhtml"
  xmlns:fo="http://www.w3.org/1999/XSL/Format"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
  xmlns:xhtml="http://www.w3.org/1999/xhtml"
  exclude-result-prefixes="fo"
  >

  <xsl:import href="style.xsl" />

  <xsl:output
    method="xml"
    indent="no"
    encoding="iso-8859-1"
    omit-xml-declaration="no"
    />

  <xsl:template match="/">
   <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format" >
    <xsl:call-template name="page-def" />
    <fo:page-sequence master-reference="page-master">
     <xsl:call-template name="static-content" />
     <fo:flow flow-name="xsl-region-body">
      <xsl:apply-templates select="//xhtml:html/xhtml:body/*">
       <xsl:with-param name="applyto">index</xsl:with-param>
      </xsl:apply-templates>
     </fo:flow>
    </fo:page-sequence>
    <fo:page-sequence master-reference="page-master">
     <xsl:call-template name="static-content" />
     <fo:flow flow-name="xsl-region-body">
      <xsl:apply-templates select="//xhtml:html/xhtml:body/*">
       <xsl:with-param name="applyto">style</xsl:with-param>
      </xsl:apply-templates>
     </fo:flow>
    </fo:page-sequence>
   </fo:root>
  </xsl:template>

  <xsl:template match="xhtml:h1">
   <xsl:param name="applyto" />
   <xsl:if test="$applyto='index'">
    <fo:block start-indent="0mm" font-size="12pt" text-align-last="justify">
     <xsl:value-of select="." />
     <fo:leader leader-pattern="dots" />Page
      <fo:basic-link internal-destination="{@id}">
       <fo:page-number-citation ref-id="{@id}" />
     </fo:basic-link>
    </fo:block>
   </xsl:if>
   <xsl:if test="$applyto='style'">
    <xsl:element name="fo:block" use-attribute-sets="h1">
     <xsl:value-of select="." />
    </xsl:element>
   </xsl:if>
  </xsl:template>

  <xsl:template match="xhtml:p">
   <xsl:param name="applyto" />
   <xsl:if test="$applyto='style'">
    <xsl:element name="fo:block" use-attribute-sets="p">
     <xsl:value-of select="." />
    </xsl:element>
   </xsl:if>
  </xsl:template>
</xsl:stylesheet>
---------------------------

After the following commands:

#xsltproc mkindex.xsl input.xhtml > /tmp/output.xhtml
#fop output.xhtml output.pdf

I get the output.pdf wich looks like this:

-----------output.pdf-------------
1. Intro .................................... Page
2. Content .................................. Page
. . . and so on . . .
-------------------------------------

But why aren't there the Page numbers where the specific h1-tags are? If i'm right you can get with <fo:basic-link internal-destination="{@id}"> the value of the id attribute of the actual node, rigth? In my case the node is h1 and the id attribute is "1.". So the value of fo:basic-link should be "1.".
And <fo:page-number-citation ref-id="{@id}" /> should go and search for a h1-tag with an id attribute with the value "1.". But it looks like there is none... or does fo:page-number-citation don't know which node is wanted?

THANKS FOR YOUR HELP
