Adding parameters to existing XSLT steps

You can pass parameters from the Ant build to existing XSLT steps in both the pre-processing pipeline and certain DITA-OT transformations. This can be useful if you want to make the parameters available as global <xsl:param> values within XSLT overrides.

1. Create an XML file that contains one or more Ant <param> elements nested within a <dummy> wrapper element.

   <dummy>
     <!-- Any Ant code allowed in xslt task is possible. Common example: -->
     <param name="paramNameinXSLT" expression="${antProperty}" if="antProperty"/>
   </dummy>

2. Construct a plugin.xml file that contains the following content:

   <plugin id="plugin-id">
     <feature extension="extension-point" file="file"/>
   </plugin>

   where:

   • plugin-id is the plug-in identifier, for example, com.example.newparam.
   • extension-point is the DITA-OT extension point, for example, dita.conductor.xhtml.param. This indicates the DITA-OT processing step where the parameters will be available.
   • file is the name of the XML file that you created in step 1, for example, insertParameters.xml.
3. Install the plug-in.

<plugin id="com.example.newparam">
  <feature extension="dita.conductor.xhtml.param" file="insertParameters.xml"/>
</plugin>
