[docbook-apps] <cx:xslthl>

[aanno <aannoaanno@gmail.com>]

Hello,

I'm looking for an example how to use/apply <cx:xslthl> xmlcalabash
extension step (https://github.com/ndw/xmlcalabash1-xslthl) on a docbook
programlistingelement when using the xslt20 stylesheets.

I know some XSLT 1.0 and there is a description how to use xslthl
directly there (https://sourceforge.net/p/xslthl/wiki/Usage/). But I'm a
bit lost on how to 'translate' that to an XProc calabash extensions step.

My best guess so far was:

<p:viewport match="db:programlisting">
  <cx:xslthl></cx:xslthl>
</p:viewport>

But this leads to the error message:

> [main] ERROR com.xmlcalabash.util.DefaultXProcMessageListener -
> src/main/resources/docbook-xsl20/db2html-db-toolchain.xpl:36:16:Required
> option not specified: highlighter
> [main] ERROR com.xmlcalabash.util.DefaultXProcMessageListener -
> src/main/resources/docbook-xsl20/db2html-db-toolchain.xpl:36:16:err:XS0018:Required
> option not specified: highlighter

Kind regards,

Thomas
