extension elements

[Joerg Baumann <Jo...@stud.informatik.uni-erlangen.de>]

Hi,

I would like to generate new markup for the result tree from my own
extensions element.
All samples I found return either a string or null.
I guess, I should create a class implementing org.w3c.dom.Element,
but I can't find a suitable Factory via
org.apache.xalan.extensions.XSLProcessorContext.

A simple Example:

XML-file:

<doc/>

XSL-rule:

<xsl:template match="/doc>
  <myext:genMarkup att="value"/>
</xsl:template>

Desired output:

<a>value</a>

Extension element:

<lxslt:script lang="javascript">
  function genMarkup(xslproc, elem) {
     val = elem.getAttribute ("att");
     // This does not work.
     // Somthing like:
     //   e = ?.createElement("a");
     //   e.setText(val);
     //   return e;
     // would be nice ;-)
     return "<a>" + val + "</a>";
  }
</lxslt:script>

Regards,
  joerg

You'll need to create a Node or NodeIterator from your favorite DOM
implementation.
