XSLT-parameter extension points

You can use theses extension points to pass parameters into existing XSLT steps in both the pre-processing pipeline and DITA-OT transformation. The parameters generally will be available as global <xsl:param> values with XSLT overrides.

Pre-processing

You can use the following extension points to pass parameters to modules in the pre-processing pipeline:

dita.preprocess.conref.param
Pass parameters to the conref module in the pre-processing pipeline
dita.preprocess.maplink.param
Pass parameters to the maplink module in the pre-processing pipeline
dita.preprocess.mappull.param
Pass parameters to the mappull module in the pre-processing pipeline
dita.preprocess.mapref.param
Pass parameters to the mapref module in the pre-processing pipeline
dita.preprocess.topicpull.param
Pass parameters to the topicpull module in the pre-processing pipeline

Transformations

You can use the following extension points to pass parameters to modules in DITA-OT transformations:

dita.conductor.eclipse.toc.param
Pass parameters to the XSLT step that generates the Eclipse Help table of contents (TOC).
dita.conductor.html.param
Pass parameters to the HTML and HTML Help transformations.
dita.conductor.pdf2.param
Pass parameters to the PDF (formerly PDF2) transformation.
dita.conductor.xhtml.param
Pass parameters to the XHTML and Eclipse Help transformations.
dita.conductor.xhtml.toc.param
Pass parameters to to the XSLT step that generates the XHTML table of contents (TOC).

Example

The following two files represent a complete (albeit simple) plug-in that passes the parameters defined in the insertParameters.xml file to the XHTML transformation process.

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

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