<blockquote>
<p>
Essentially an XML transformation tool, Anakia uses <a href="http://www.jdom.org">JDOM</a> and <a href="http://jakarta.apache.org/velocity">Velocity</a> to transform
XML documents into the format of your choice. It provides an alternative to
using Ant's <style> task and
<a href="http://xml.apache.org/xalan/">XSL</a> to process XML
files.
</p>
<p>
The basic model that AnakiaTask uses is pretty straightforward :
<ol>
<li>Parse your XML into a JDOM Document:<br />
<pre>SAXBuilder builder;
Document root = null;
try
{
builder = new SAXBuilder(
"org.apache.xerces.parsers.SAXParser" );
root = builder.build( file );
}
catch( Exception )
{
System.out.println( ... );
}</pre></li>
<li>Stuff the Document (or root Element) into the context:<br />
<pre>context.put("root", root );</pre></li>
<li>Render a template using Velocity. Within the template, one
can use JDOM's methods to access the data contained in the
XML document.</li>
</ol>
</p>
<p>
Anakia is potentially easier to learn than XSL, but it maintains a
similar level of functionality. Learning cryptic <xsl:> tags
is unnecessary; you only need to know how to use the provided
Context objects, JDOM, and Velocity's simple directives. Anakia
seems to perform much faster than Xalan's XSL processor at creating
pages. (23 pages are generated in 7-8 seconds on a PIII 500mhz
running Win98 and JDK 1.3 with client Hotspot. A similar system
using Ant's <style> task took 14-15 seconds -- nearly a 2x
speed improvement.)
</p>
<p>
Anakia -- intended to replace Stylebook, which was originally used
to generate simple, static web sites in which all pages had the same
look and feel -- is great for documentation/project web sites, such
as the sites on <a href="http://www.apache.org/">www.apache.org</a>
and <a href="http://jakarta.apache.org">jakarta.apache.org</a>. As it
is more targeted to a specific purpose, it does not provide some of
XSL's "extra" functionality.
</p>
<p>
The example in the jakarta-velocity/examples/anakia directory
provides a good introduction to Anakia. You should find it quite
simple to use.
</p>
<p>
Anakia creates a Context, which contains a JDOM Document object of
the .xml page, as well as an (optional) JDOM Document object of your
project.xml page. The .vsl page is executed (using Velocity) with
the Context. You can then navigate your .xml file and pull
information out of it by simply executing methods on the JDOM
Document object.
</p>
<p>
Anakia is being used to create the documentation for not only this
website, but also for the Jakarta Project's website as well as
many of the projects that live under the Jakarta Project. This
process is
<a href="http://jakarta.apache.org/site/jakarta-site2.html">documented</a>
on the site. You are welcome to use this for your own needs as well.

<p>
Before reviewing the jakarta-velocity/examples/anakia directory,
you must <a href="install.html">build Velocity</a>.
</p>
<p>
After building Velocity, <code>cd</code> into the
jakarta-velocity/examples/anakia/build directory and run 'ant'.
</p>
<p>
Output from running ant, in this case HTML files, is placed
into the jakarta-velocity/examples/anakia/docs/ directory.
</p>
<p>
The jakarta-velocity/examples/anakia/xdocs/ directory has all of the
.xml source code. The xdocs/stylesheets directory contains the .vsl
file, in which most of the magic happens. Understanding <a href="user-guide.html">Velocity Template Language</a> and
<a href="http://www.jdom.org/">JDOM</a> is
necessary to understand how the .vsl file works.

This turns on or off the ability to check the last

they need to be re-rendered or not. The value of this

true, meaning that the last modified date should be checked

This will allow you to walk a tree of JDOM Element

you can look at each Element node conditionally and set its

more "ugly" aspects of Anakia, but it does do the
job and suggestions for improvement are appreciated. This
context object is still under development and more
documentation will follow soon. NOTE: this object is obsolete and

object in a JDOM object tree, such as an org.jdom.Element,
org.jdom.Document, or org.jdom.Attribute. Please see the .vsl
example file and the org.apache.velocity.anakia.XPathTool javadoc

All node lists returned from Anakia objects through $element.selectNodes,
$element.content, and $element.children, as well as through obsoleted
$treeWalk.allElements and $xpath.applyTo have two special features:
<ul>
<li>they support the selectNodes method just as a single element does
that applies an XPath expression to all nodes in the list, and</li>
<li>when inserted into template output by simply specifying $list, they
produce the XML fragment consisting of all nodes they contain. This
eliminates much of the #foreach code in templates.</li>

Anakia was originally conceptualized and implemented by
<a href="mailto:jon@latchkey.com">Jon S. Stevens</a>.
</p>
<p>
The name <a href="http://www.kabalarians.com/female/anakia.htm">Anakia</a> is a
cool name that I think fits this project quite nicely. "The name of
Anakia has given you the desire for creative, artistic or musical
expression in an original way. You strive to be different and have
the self-confidence to implement your ideas because you have the
perseverance necessary to see something through, despite obstacles."
</p>
<p>
Further help and assistance was provided by Jason van Zyl and Geir
Magnusson Jr. XPath support was added by Bob McWhirter. The more
intuitive syntax achieved through selectNodes() and self-rendering
elements and node lists was added by Attila Szegedi.
