<div class="paragraph"><p>Codiicsa is an extendable Python program for converting Docbook XML to the
Asciidoc markup language.</p></div>
<div class="paragraph"><p>By default it is configured to reverse Docbook with the conventions used in
Docbook generated by Asciidoc but configuration will usually be needed for
documents using other conventions.</p></div>
<div class="paragraph"><p>Codiicsa is in its initial stages of development but so far it converts
nested sections, simple lists, some text markup and some blocks.</p></div>

<h2 id="_design_notes">Design Notes</h2>
<div class="sectionbody">
<div class="paragraph"><p>Codiicsa operates by parsing the input Docbook into a tree and then generates
the output during a depth-first tree walk. The output is kept in memory so that
the processing for a node can edit the output of its children if needed.</p></div>
<div class="sect2">
<h3 id="_peculiarities_of_elementtree">Peculiarities of ElementTree</h3>
<div class="paragraph"><p>Codiicsa uses the ElementTree parser which has some particular impacts on
the processing of the resulting tree. The contents of each XML element is
stored as:</p></div>
<div class="ulist"><ul>
<li>
<p>
the initial text in the <em>text</em> attribute on the node representing the
element, and
</p>
</li>
<li>
<p>
a list of child nodes.
</p>
</li>
</ul></div>
<div class="paragraph"><p>Text between the child nodes which is actually part of the text in <em>elem</em> is
contained in the <em>tail</em> attributes on the child nodes.</p></div>
<div class="paragraph"><p>If <em>elem</em> represents a node which does not contain text (either by Docbook
rules or by convention) then the <em>tail</em> attributes can be ignored since they
are just whitespace to make the Docbook look nice (Asciidoc generates a lot
of this).</p></div>
<div class="paragraph"><p>But if <em>elem</em> represents a node that can contain text care must be taken to
ensure that the when <em>elem</em> is processed the <em>tails</em> of its <strong>children</strong> are
processed. The <em>tail</em> of <em>elem</em> itself is outside its closing tag and is not
part of its processing.</p></div>
<div class="paragraph"><p>Attributes of <em>ElementTree</em> that can be useful in your processing:</p></div>
<div class="ulist"><ul>
<li>
<p>
elem.<em>text</em> contains the text as described above.
</p>
</li>
<li>
<p>
elem.<em>tail</em> contains text following the elements close tag.
</p>
</li>
<li>
<p>
elem.<em>get( <em>name</em> )</em> gets the XML attribute value for the attribute
<em>name</em> or <em>None</em> if the element doesn’t have that attribute.
</p>
</li>
</ul></div>
</div>
<div class="sect2">
<h3 id="_the_em_out_em_class">The <em>Out</em> class</h3>
<div class="paragraph"><p>Codiicsa accumulates its output as a list of strings rather than catenating
it into a single string since Python string handling might generate a whole
new string each time a modification is made (or it might not, depends on
exact circumstances).</p></div>
<div class="paragraph"><p>The <em>Out</em> class is a convenience wrapper for a list that makes it simpler to add
strings, and <em>Out</em> objects, eg those returned from processing child nodes.</p></div>
<div class="paragraph"><p>The <em>Out</em> constructor takes either a string or a list of strings as the initial
list of strings.</p></div>
<div class="paragraph"><p><em>Out</em>, and string objects can be combined using the <em>+</em> operator making it
convenient to express a sequence of output, for example the code to generate
the Asciidoc link syntax:</p></div>

<div class="content">

<div class="paragraph"><p>Please read the design notes section, this provides some useful information
to understand the process.</p></div>
<div class="paragraph"><p>Codiicsa specifies all processing using a Python class with methods
named to match the Docbook element names. When an element is

<div class="paragraph"><p>This allows extension or overriding in the way that cascading style sheets
or the Asciidoc configuration files work. Methods in a child class are added
to the class or override an existing method of the same name. You don’t need
to change the original to configure it.</p></div>
<div class="paragraph"><p>As a concrete (but silly) example lets output <em>bibliorefs not handled</em> when a
