<h2><a name="style">Style</a></h2>
<h3>Description</h3>
<p>Process a set of documents via XSLT.</p>
<p>This is useful for building views of XML based documentation,
or in generating code.</p>
<p>It is possible to refine the set of files that are being copied. This can be
done with the <i>includes</i>, <i>includesfile</i>, <i>excludes</i>, <i>excludesfile</i> and <i>defaultexcludes</i>
attributes. With the <i>includes</i> or <i>includesfile</i> attribute you specify the files you want to
have included by using patterns. The <i>exclude</i> or <i>excludesfile</i> attribute is used to specify
the files you want to have excluded. This is also done with patterns. And
finally with the <i>defaultexcludes</i> attribute, you can specify whether you
want to use default exclusions or not. See the section on <a
href="../dirtasks.html#directorybasedtasks">directory based tasks</a>, on how the
inclusion/exclusion of files works, and how to write patterns.</p>
<p>This task forms an implicit <a href="../CoreTypes/fileset.html">FileSet</a> and supports all 
  attributes of <code>&lt;fileset&gt;</code> (<code>dir</code> becomes <code>basedir</code>) 
  as well as the nested <code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code> 
  and <code>&lt;patternset&gt;</code> elements.</p>
<p>Style supports the use of a &lt;param&gt; element which is used to pass values 
  to an &lt;xsl:param&gt; declaration.</p>

      specified.</td>
  </tr>
  <tr>
    <td valign="top">extension</td>
    <td valign="top">desired file extension to be used for the targets. If not

  </tr>
  <tr>
    <td valign="top">style</td>
    <td valign="top">name of the stylesheet to use - given either relative
      to the project's basedir or as an absolute path
      <em><strong>DEPRECATED</strong> - can be specified as a path relative

<h3>Examples</h3>
<blockquote>
  <pre>
&lt;style basedir=&quot;doc&quot; destdir=&quot;build/doc&quot;
       extension=&quot;html&quot; style=&quot;style/apache.xsl&quot;/&gt;</pre>
  <h4>Using XSL parameters</h4>
  <pre>&lt;style basedir=&quot;doc&quot; destdir=&quot;build/doc&quot;
		extension=&quot;html&quot; style=&quot;style/apache.xsl&quot;&gt;
	&lt;param name=&quot;date&quot; expression=&quot;'07-01-2000'&quot;/&gt;
