Xslt/Style

Description

Process a set of documents via XSLT.

This is useful for building views of XML based documentation, or for generating code.

Note: This task depends on external libraries not included in the Ant distribution. See Library Dependencies for more information.

It is possible to refine the set of files that are being processed. This can be done with the includes, includesfile, excludes, excludesfile and defaultexcludes attributes. With the includes or includesfile attribute you specify the files you want to have included by using patterns. The exclude or excludesfile attribute is used to specify the files you want to have excluded. This is also done with patterns. And finally with the defaultexcludes attribute, you can specify whether you want to use default exclusions or not. See the section on directory based tasks, on how the inclusion/exclusion of files works, and how to write patterns.

This task forms an implicit FileSet and supports all attributes of <fileset> (dir becomes basedir) as well as the nested <include>, <exclude> and <patternset> elements.

This task supports the use of a nested <param> element which is used to pass values to an <xsl:param> declaration.

element which is used to perform Entity and URI resolution

<style> and <xslt> refer to the same Ant task and can be used interchangeably.

If you want to use Xalan-J 1 or XSL:P, you also need Ant's optional.jar

Parameters

Attribute Description Required
basedir where to find the source XML file, default is the project's basedir. No
destdir directory in which to store the results. Yes, unless in and out have been specified.
extension desired file extension to be used for the targets. If not specified, the default is ".html". No
style name of the stylesheet to use - given either relative to the project's basedir or as an absolute path DEPRECATED - can be specified as a path relative to the basedir attribute of this task as well. Yes
classpath the classpath to use when looking up the XSLT processor. No
classpathref the classpath to use, given as reference to a path defined elsewhere. No
force Recreate target files, even if they are newer than their corresponding source files or the stylesheet. No; default is false
processor name of the XSLT processor to use. Permissible values are "trax" for a TraX compliant processor (ie JAXP interface implementation such as Xalan 2 or Saxon), "xslp" for the XSL:P processor, "xalan" for the Apache XML Xalan (version 1) processor the name of an arbitrary XSLTLiaison class. Defaults to trax, followed by xalan and then xslp (in that order). The first one found in your class path is the one that is used. DEPRECATED - XSL:P and xalan are deprecated and no more supported.. No
includes comma- or space-separated list of patterns of files that must be included. All files are included when omitted. No
includesfile the name of a file. Each line of this file is taken to be an include pattern No
excludes comma- or space-separated list of patterns of files that must be excluded. No files (except default excludes) are excluded when omitted. No
excludesfile the name of a file. Each line of this file is taken to be an exclude pattern No
defaultexcludes indicates whether default excludes should be used or not ("yes"/"no"). Default excludes are used when omitted. No
in specifies a single XML document to be styled. Should be used with the out attribute. No
out specifies the output name for the styled result from the in attribute. No
scanincludeddirectories If any directories are matched by the includes/excludes patterns, try to transform all files in these directories. Default is true No

Parameters specified as nested elements

classpath

The classpath to load the processor from can be specified via a nested <classpath>, as well - that is, a path-like structure.

element is used to perform Entity and URI resolution.

param

Param is used to pass a parameter to the XSL stylesheet.

Parameters

Attribute Description Required
name Name of the XSL parameter Yes
expression XSL expression to be placed into the param. To pass a text value into the style sheet it needs to be escaped using single quotes. Yes

outputproperty ('trax' processors only)

Used to specify how you wish the result tree to be output as specified in the XSLT specifications.

Parameters

Attribute Description Required
name Name of the property Yes
value value of the property. Yes

Examples


<style basedir="doc" destdir="build/doc"

       extension=".html" style="style/apache.xsl"/>
<xslt basedir="doc" destdir="build/doc"

      extension=".html" style="style/apache.xsl">


</xslt>



<xslt basedir="doc" destdir="build/doc"

   extension=".html" style="style/apache.xsl">


       <dtd 

         publicId="-//ArielPartners//DTD XML Article V1.0//EN"

         location="com/arielpartners/knowledgebase/dtd/article.dtd"/>


</xslt>

Using XSL parameters

<xslt basedir="doc" destdir="build/doc"

      extension=".html" style="style/apache.xsl">

  <param name="date" expression="07-01-2000"/>

</xslt>

Then if you declare a global parameter "date" with the top-level element <xsl:param name="date"/>, the variable $date will subsequently have the value 07-01-2000.

Using output properties

style="style/apache.xsl"> <outputproperty name="standalone" value="yes"/> <outputproperty name="encoding" value="iso8859_1"/> <outputproperty name="indent" value="yes"/> </xslt>
