- 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><div class="section"><a name="d0e1006"></a><div class="titlepage"><div><h2 class="title" style="clear: both"><a name="d0e1006"></a>Changing the Article Title Page</h2></div></div><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 <span class="emphasis"><i>how</i></span> 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></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="ch04.html">Prev</a> </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right"> </td></tr><tr><td width="40%" align="left">Chapter 4.
