Add bookmark on docbook PDF

In this article I'll discuss two points about docbook that generate to PDF.I use the ant to generate docbook,following is my ant file.

<!--

- target: build-pdf

- description: Iterates through a directory and transforms

- .xml files into .fo files which can then be turned into DocBook XML

- files.

-->

<target name="build-pdf" depends="depends"

description="Generates PDF files from DocBook XML">

<xslt style="${fo.stylesheet}" extension=".fo"

basedir="${basedir}/src" destdir="${target.dir}/fo">

<classpath refid="xalan.classpath" />

<include name="**/*.xml" />

<exclude name="**/*chapter*.xml"/>

</xslt>





<property name="fop.home" value="${basedir}/lib/fop-0.95"/>

<taskdef name="fop" classname="org.apache.fop.tools.anttasks.Fop">

<classpath>

<fileset dir="${fop.home}/lib">

<include name="*.jar"/>

</fileset>

<fileset dir="${fop.home}/build">

<include name="fop.jar" />

</fileset>

</classpath>

</taskdef>



<fop format="application/pdf"

outdir="${target.dir}/pdf" basedir="${target.dir}/fo">

<fileset dir="${target.dir}/fo">

<include name="*.fo"/>

</fileset>

</fop>







</target>

following is my dobook segment:
<sect1>

<title>Section 1 title</title>

<para>

<sect2>

<title>section 2 title</title>

<para>

description...

</para>

<sect3>

<para>witing something...</para>

<sect3>

</sect2>

</sect1>

Now the question is;
1)I want to display the label of section.
2)I want to display the bookmark in PDF.

The final solution is change the param.xml file.
1)to display the label of section:
change following line
<xsl:param name="section.autolabel" select="0">

to this line

<xsl:param name="section.autolabel" select="1">



2)to display the bookmark in PDF.

change following line

<xsl:param name="fop1.extensions" select="0">

to this line

<xsl:param name="fop1.extensions" select="1">


Note:don't change following line otherwise you will get an exception like:
No element mapping definition found for (Namespace URI: "http://xml.apache.org/fop/extensions", Local Name: "destination")

<xsl:param name="fop.extensions" select="0">
