<title>XSLT Task</title>
</head>
<body>
<h2 id="style">XSLT</h2>
<p><em>The name <code>style</code> is a <u>deprecated</u> name for the same task.</em></p>
<h3>Description</h3>
<p>Process a set of documents via XSLT.</p>
<p>This is useful for building views of XML based documentation, or for generating code.</p>
<p>It is possible to refine the set of files that are being processed. This can be done with
the <var>includes</var>, <var>includesfile</var>, <var>excludes</var>, <var>excludesfile</var>
and <var>defaultexcludes</var> attributes. With the <var>includes</var> or <var>includesfile</var>
attribute you specify the files you want to have included by using patterns. The <var>exclude</var>
or <var>excludesfile</var> attribute is used to specify the files you want to have excluded. This is
also done with patterns. And finally with the <var>defaultexcludes</var> 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="../Types/fileset.html">FileSet</a> and supports all
attributes of <code>&lt;fileset&gt;</code> (<var>dir</var> becomes <var>basedir</var>) as well
as the nested <code>&lt;include&gt;</code>, <code>&lt;exclude&gt;</code>
and <code>&lt;patternset&gt;</code> elements.</p>
<p><strong>Note</strong>: Unlike other similar tasks, this task treats directories that have been
matched by the include/exclude patterns of the implicit fileset in a special way. It will apply the
stylesheets to all files contain in them as well. Since the default <var>includes</var> pattern
is <code>**</code> this means it will apply the stylesheet to all files. If you specify
an <var>excludes</var> pattern, it may still work on the files matched by those patterns because the
parent directory has been matched. If this behavior is not what you want, set
the <var>scanincludedirectories</var> attribute to <q>false</q>.</p>
<p><em>Since Ant 1.7</em>, this task supports
nested <a href="../Types/resources.html#collection">resource collections</a> in addition to (or
instead of, depending on the <var>useImplicitFileset</var> attribute) the implicit fileset formed by
this task.</p>
<p>This task supports the use of a nested <code>&lt;param&gt;</code> element which is used to pass
values to an <code>&lt;xsl:param&gt;</code> declaration.</p>
<p>This task supports the use of a nested <a href="../Types/xmlcatalog.html">xmlcatalog</a> element
which is used to perform Entity and URI resolution.</p>
<p><strong>Note on XSLT extension functions</strong>: when using the default TrAX implementation of
the Java class library and a <code>SecurityManager</code> is active&mdash;e.g. when running from
within an IDE&mdash;XSLT extension functions cannot be used as "secure processing" is active in Java
7 and above. Ant contains a special "hack" that allows XSLT extensions to be used in Java 7 and 8,
but this hack fails for Java 9. If you want to use extensions like the redirect extension that are
provided by the Java class library itself, you can allow them by enabling the
feature <var>http://www.oracle.com/xml/jaxp/properties/enableExtensionFunctions</var> in Java 9 and
above. If you need to use an extension function not provided by Java itself you can set the
attribute <var>jdk.xml.transform.extensionClassLoader</var> to a classloader (reference to an Ant
path-like structure).</p>

<h3>Parameters specified as nested elements</h3>
<h4>any <a href="../Types/resources.html#collection">resource collection</a></h4>
<p><em>Since Ant 1.7</em></p>
<p>Use resource collections to specify resources that the stylesheet should be applied to. Use a
nested mapper and the task's <q>destdir</q> attribute to specify the output files.</p>
<h4 id="classpath">classpath</h4>
<p>The classpath to load the processor from can be specified via a
nested <code>&lt;classpath&gt;</code>, as well&mdash;that is,
a <a href="../using.html#path">path-like structure</a>.</p>
<h4>xmlcatalog</h4>
<p>The <a href="../Types/xmlcatalog.html">xmlcatalog</a> element is used to perform Entity and URI
resolution.</p>
<h4>param</h4>
<p><code>Param</code> is used to pass a parameter to the XSL stylesheet.</p>
<h5>Parameters</h5>
<table class="attr">
<tr>
<th scope="col">Attribute</th>
<th scope="col">Description</th>
<th scope="col">Required</th>
</tr>
<tr>
<td>name</td>
<td>Name of the XSL parameter</td>

<tr>

<td>The value to be placed into the param or an XPath expression (depending
on <var>type</var>).</td>
<td>Yes</td>
</tr>
<tr>
<td>type</td>
<td>Data type of the parameter. Possible values are:
<ul>
<li><q>STRING</q></li>
<li><q>BOOLEAN</q></li>
<li><q>INT</q></li>
<li><q>LONG</q></li>
<li><q>DOUBLE</q></li>
<li><q>XPATH_STRING</q></li>
<li><q>XPATH_BOOLEAN</q></li>
<li><q>XPATH_NUMBER</q></li>
<li><q>XPATH_NODE</q></li>
<li><q>XPATH_NODESET</q></li>
</ul><em>since Ant 1.9.3</em>
</td>
<td>No; default is <q>STRING</q></td>
</tr>
<tr>
<td>if</td>
<td>The param will only be passed <a href="../properties.html#if+unless">if this property is
set</a>.</td>
<td>No</td>
</tr>
<tr>
<td>unless</td>
<td>The param will not be passed <a href="../properties.html#if+unless">if this property is
set</a>.</td>
<td>No</td>
</tr>
</table>
<p>The <q>XPATH_*</q> types says that the <var>expression</var> is not just a primitive-type value
but an XPath expression. This expression will be evaluated on an empty XML document and the result
will be passed to the XSLT transformer as a parameter of given type. In these expressions the
declared Ant properties can be used as XPath variables e.g. <code>$someProperty</code>. So you can
compute something using standard XPath functions and operators.</p>
<p>If you write <code>${someProperty}</code> instead of <code>$someProperty</code>, the value will
be simply substituted by Ant before evaluating the XPath expression (this substitution works also
for primitive types).</p>
<h4>outputproperty (<var>trax</var> processors only)</h4>
<p>Used to specify how you wish the result tree to be output as specified in
the <a href="https://www.w3.org/TR/xslt#output" target="_top">XSLT specifications</a>.

<h4>mapper</h4>
<p><em>Since Ant 1.6.2</em></p>
<p>You can define filename transformations by using a
nested <a href="../Types/mapper.html">mapper</a> element. The default mapper used
by <code>&lt;xslt&gt;</code> removes the file extension from the source file and adds the extension
specified via the extension attribute.</p>
<h4>style</h4>
<p><em>Since Ant 1.7</em></p>
<p>The nested <code>style</code> element can be used to specify your stylesheet in terms of
Ant's <a href="../Types/resources.html">resource</a> types. With this element, the stylesheet
should be specified as a nested resource or single-element collection. Alternatively, use
the <var>refid</var> to specify the resource or collection as a reference.</p>
<h4>sysproperty</h4>
<p><em>Since Ant 1.8.0</em>.</p>
<p>Use nested <code>&lt;sysproperty&gt;</code> elements to specify system properties required by the
factory or transformation. These properties will be made available to JVM during the execution of
the class. The attributes for this element are the same as for <a href="exec.html#env">environment
variables</a>.</p>
<h4>syspropertyset</h4>
<p><em>Since Ant 1.8.0</em>.</p>
<p>You can specify a set of properties to be used as system properties
with <a href="../Types/propertyset.html">syspropertyset</a>s.</p>
<h3>Examples</h3>
<pre>
&lt;xslt basedir=&quot;doc&quot; destdir=&quot;build/doc&quot;

&lt;param name=&quot;date&quot; expression=&quot;07-01-2000&quot;/&gt;
&lt;/xslt&gt;</pre>
<p>Then if you declare a global parameter <q>date</q> with the top-level element <code>&lt;xsl:param
name=&quot;date&quot;/&gt;</code>, the variable <code>$date</code> will subsequently have the value
07-01-2000.</p>

&lt;property name="antProperty2" value="ANT_PROPERTY_2"/&gt;
&lt;property name="antProperty3" value="3"/&gt;
