|
|
using XSL Stylesheets. In particular, the formatting of title pages
|
|
is generated using a special template system. The same template system
|
|
will eventually allow you to easily customize bibliography entries and
|
|
perhaps other parts of the system as well.</p><p>FIXME: there needs to be more introductory/explanatory text
|
|
here!</p><p>In order to demonstrate how this system works, let's consider
|
|
how we can use it to change the format of article title pages.</p><p>By default, the stylesheets print the following elements on the
|
|
article title page, in this order: <span class="simplelist"><tt>title</tt>, <tt>subtitle</tt>, <tt>corpauthor</tt>, <tt>authorgroup</tt>, <tt>author</tt>, <tt>releaseinfo</tt>, <tt>copyright</tt>, <tt>legalnotice</tt>, <tt>pubdate</tt>, <tt>revision</tt>, <tt>revhistory</tt>, <tt>abstract</tt></span>. Suppose we want to put only the
|
|
<tt>title</tt>, <tt>author</tt>, and
|
|
<tt>edition</tt> elements on the title page, in the order
|
|
that they appear in the <tt>articleinfo</tt>.
|
|
</p><p>The “hard” (and wrong!) way to do it would be to
|
|
edit <tt>titlepage.templates.xsl</tt> and make the changes
|
|
by hand.</p><p>The easy and right way is to construct a template document that
|
|
describes the order and sequence of elements that you want:</p><pre class="screen">
|
|
<t:templates xmlns:t="http://nwalsh.com/docbook/xsl/template/1.0"
|
|
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
|
|
base-stylesheet="/path/to/html/docbook.xsl">
|
|
|
|
<t:titlepage element="article" wrapper="div" class="titlepage">
|
|
<t:titlepage-content side="recto" order="document">
|
|
<title predicate="[1]"/>
|
|
<author/>
|
|
<edition/>
|
|
</t:titlepage-content>
|
|
</t:titlepage>
|
|
</t:templates>
|
|
</pre><p>Then process this document with the
|
|
<tt>template/titlepage.xsl</tt> stylesheet. This will
|
|
produce the following somewhat cryptic stylesheet:</p><pre class="screen">
|
|
<?xml version="1.0" encoding="utf-8"?>
|
|
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
|
|
|
|
<!-- This stylesheet was created by titlepage.xsl; do not edit it by hand. -->
|
|
|
|
<xsl:import href="/path/to/html/docbook.xsl"/>
|
|
|
|
<xsl:template name="article.titlepage.recto"><xsl:apply-templates mode="article.titlepage.recto.mode" select="(articleinfo/title|artheader/title|title)[1]|articleinfo/author|artheader/author|articleinfo/edition|artheader/edition"/>
|
|
</xsl:template>
|
|
|
|
<xsl:template name="article.titlepage">
|
|
<div class="titlepage">
|
|
<xsl:call-template name="article.titlepage.before.recto"/>
|
|
<xsl:call-template name="article.titlepage.recto"/>
|
|
<xsl:call-template name="article.titlepage.before.verso"/>
|
|
<xsl:call-template name="article.titlepage.verso"/>
|
|
<xsl:call-template name="article.titlepage.separator"/>
|
|
</div>
|
|
</xsl:template>
|
|
|
|
</xsl:stylesheet>
|
|
</pre><p>Despite its cryptic appearance, it has the desired result.
|
|
If you want to change <i>how</i> the titlepage elements
|
|
are formatted (as opposed to which ones are formatted), you have to
|
|
write your own customization layer that overrides the template for
|
|
the element in question in the “titlepage.mode” mode.</p><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a href="ch03.html">Prev</a> </td><td width="20%" align="center"><a href="index.html">Home</a></td><td width="40%" align="right"> </td></tr><tr><td width="40%" align="left">Chapter 3.
