This is what I was alluding to in my earlier message.  It's not a Xalan
bug.  The context node for a template comes from the current node for
the template.  The current node for the template is basically the node
which caused the template to be chosen.  In your case, that is the
<TRACK> node.  So, you'll get all of the children of the <TRACK> node. 
The text nodes that you're seeing with just a newline for content are
the whitespace nodes between the various elements that are the children
of <TRACK>.

If I were you, I'd shelve the extension element and create an extension
function, passing the text time, like this:

  <PLAYTIME>
    <xsl:value-of select="rioport:min2sec(string(TRACK_PLAYTIME))"/>
  </PLAYTIME>

I think this is what you want to do.

XSLTProcessor xsltproc=XSLTProcessorFactory.getProcessor(new
XMLParserLiaison());

StringWriter stringwriter=new StringWriter();
String xmlname="stamps.xml";
String xslname="stampTest.xsl";
String filename1=application.getRealPath("/xml/"+xmlname);
String filename2=application.getRealPath("/xml/"+xslname);
FileReader filereader=new FileReader(filename1);

XSLTInputSource xsltinputsource=new XSLTInputSource(filereader);
XSLTInputSource xsltinputsource1=new XSLTInputSource(filename2);
XSLTResultTarget xsltresulttarget=new XSLTResultTarget(stringwriter);
xsltproc.process(xsltinputsource,xsltinputsource1,xsltresulttarget);
String output=stringwriter.toString();
%>
