<h1>Site Layout</h1>
<p>Breaking all of the web pages into separate XML
documents introduces a significant problem: the
hierarchical structure of the website is no longer
manifest in the source document.</p>
<p>In order for the stylesheets to construct the
navigation system, you must describe the desired
hierarchy explicitly in a <span class=
"emphasis"><em>layout</em></span> file. The layout
file, which must conform to <tt class=
"filename">layout.dtd</tt>, identifies all of the pages
in the website and defines how they fit into the
navigational hierarchy. Here is simple layout file:</p>
<pre class="programlisting">
<?xml version="1.0"?>
<layout>
<toc page="website.xml" filename="index.html">
<tocentry page="doc1.xml" filename="page1.html"/>
<tocentry page="doc2.xml" filename="page2.html"/>
</toc>
</layout>
</pre>
<p>This website has three pages:</p>
<div class="orderedlist">
<ol type="1">
<li>
<p><tt class="filename">index.html</tt>,
generated from <tt class=
"filename">website.xml</tt>;</p>
</li>
<li>
<p><tt class="filename">page1.html</tt>,
generated from <tt class=
"filename">doc1.xml</tt>; and</p>
</li>
<li>
<p><tt class="filename">page2.html</tt>,
generated from <tt class=
"filename">doc2.xml</tt></p>
</li>
</ol>
</div>
<p>(See also: <a href="revflag.html" target=
"_top">revision flags</a>)</p>
<p>Using this layout file, the hierarchical structure
of the website is a main page <tt class=
"filename">index.html</tt> with two subordinate pages
that are siblings:</p>
<pre class="programlisting">
+ index.html
+ page1.html
+ page2.html
</pre>
<p>Here's a slightly more complicated example:</p>
<pre class="programlisting">
<?xml version="1.0"?>
<layout>
<toc page="website.xml" filename="index.html">
<tocentry page="doc1.xml" dir="subdir"
filename="index.html">
<tocentry page="doc1.1.xml" filename="page2.html"/>
<tocentry page="doc1.2.xml" filename="page3.html"/>
</tocentry>
<tocentry page="doc2.xml" filename="page2.html"/>
</toc>
</layout>
</pre>
<p>This website has five pages:</p>
<div class="orderedlist">
<ol type="1">
<li>
<p><tt class="filename">index.html</tt>,
generated from <tt class=
"filename">website.xml</tt>;</p>
</li>
<li>
<p><tt class="filename">subdir/index.html</tt>,
generated from <tt class=
"filename">doc1.xml</tt>;</p>
</li>
<li>
<p><tt class="filename">subdir/page2.html</tt>,
generated from <tt class=
"filename">doc1.1.xml</tt>;</p>
</li>
<li>
<p><tt class="filename">subdir/page3.html</tt>,
generated from <tt class=
"filename">doc1.2.xml</tt>; and</p>
</li>
<li>
<p><tt class="filename">page2.html</tt>,
generated from <tt class=
"filename">doc2.xml</tt></p>
</li>
</ol>
</div>
<p>Using this layout file, the hierarchical structure
of the website is a main page <tt class=
"filename">index.html</tt> with two subordinate pages
that are siblings (<tt class=
"filename">subdir/index.html</tt> and <tt class=
"filename">page2.html</tt>). The first sibling page has
two siblings of its own (<tt class=
"filename">subdir/page2.html</tt> and <tt class=
"filename">subdir/page3.html</tt>):</p>
<pre class="programlisting">
+ index.html
+ subdir/index.html
+ subdir/page2.html
+ subdir/page3.html
+ page2.html
</pre>
<p>In brief, the hierarchy of <tt class=
"sgmltag-element">tocentry</tt> elements in a <tt
class="sgmltag-element">toc</tt> describes the logical
navigation hierarchy of the website. Each entry must
identify the XML document (containing a <tt class=
"sgmltag-starttag"><webpage></tt>) that it
represents and may identify the directory and filename
where the file will appear in the HTML website.</p>
<p>By default, directories are inherited (hence <tt
class="filename">page2.html</tt> and <tt class=
"filename">page3.html</tt> will appear in the <tt
class="filename">subdir</tt> directory) which makes it
easy to build a website that has similar logical and
physical organization. It is not necessary for the
logical and physical hierarchy of your website to be
consistent; you can specify an absolute directory at
any level and on any file by beginning the name with a
slash.</p>
<p>If a directory is not specified, the files will
appear in the currently inherited directory (or in the
root, if no directory is specified anywhere in the <tt
class="sgmltag-element">tocentry</tt> ancestry).</p>
<p>If a filename is not specified, <tt class=
"filename">index.html</tt> will be used.</p>
<p>It is possible to map two different XML documents to
the same HTML filename. At present, the stylesheets do
not detect this, but the result will be a broken
website. Exercise caution.</p>
<div class="section" lang="en">
<div class="titlepage">
<div>
<div>
<h2 class="title" style="clear: both"><a name=
"d0e173"></a>Global Parameters</h2>
</div>
</div>
</div>
<p>The layout file can also contain a number of
global parameters: <tt class=
"sgmltag-element">config</tt>, <tt class=
"sgmltag-element">script</tt>, <tt class=
"sgmltag-element">style</tt>, and <tt class=
"sgmltag-element">copyright</tt>. For the most part,
these elements behave as they do on individual pages,
except that they apply to every page.</p>
</div>
<div class="section" lang="en">
<div class="titlepage">
<div>
<div>
<h2 class="title" style="clear: both"><a name=
"d0e192"></a>Multiple <tt class=
"sgmltag-element">toc</tt>s</h2>
</div>
</div>
</div>
<p>If you put multiple <tt class=
"sgmltag-element">toc</tt> elements in your layout
file, the result will be completely separate
navigational hierarchies. Note, however, that the
restriction that a page can only appear once in a
website prevents a page from appearing in more than
one hierarchy.</p>
<p>Navigation between hierarchies is only possible if
you insert <a href="linking.html">links between
pages</a> across hierarchies.</p>
</div>
<div class="section" lang="en">
<div class="titlepage">
<div>
<div>
<h2 class="title" style="clear: both"><a name=
"d0e211"></a>Standalone Pages</h2>
</div>
</div>
</div>
<p>Pages identified with <tt class=
"sgmltag-element">notoc</tt> elements instead of <tt
class="sgmltag-element">tocentry</tt>s will be in the
website but will not appear in any hierarchy. The <a
href="about.html">about page</a> of this example
website uses <tt class=
"sgmltag-element">notoc</tt>.</p>
</div>
<div class="section" lang="en">
<div class="titlepage">
<div>
<div>
<h2 class="title" style="clear: both"><a name=
"d0e230"></a>“<span class=
"quote">Dummy</span>” Pages</h2>
</div>
</div>
</div>
<p>Sometimes it's useful to have a page in the
hierarchy in order to make the TOC clearer, without
actually wanting to construct the page. Consider the
“<span class="quote">Building</span>”
page in this website. It's really just a hierarchy
placeholder for the different sorts of building that
are possible.</p>
<p>If you click on “<span class=
"quote">Building</span>” in the TOC, you'll
discover that you don't actually go to that page,
instead you go to that page's first child.</p>
<p>This effect is achieved by using the <tt class=
"sgmltag-attribute">tocskip</tt> attribute on the <tt
class="sgmltag-element">tocentry</tt> for the
building page.</p>
<p>Note, however, that the skipped page must exist
and it is still possible to link directly to <a href=
"building.html">the page</a>.</p>
