Hi,

(btw, this is becoming a faq but I cant find it on dave's or jeni's sites

does it warrant being added?)

yes, its possible pass parameters into stylesheets using javascript.

Using msxml4:

  function load()
  {
     xml  = new ActiveXObject("Msxml2.DOMDocument.4.0");
     xml.async = false;
     xml.load("youXMLfile.xml");

     xsl = new ActiveXObject("Msxml2.FreeThreadedDOMDocument.4.0");
     xsl.async = false;
     xsl.load("yourXSLfile.xsl");

     template = new ActiveXObject("Msxml2.XSLTemplate.4.0");
     template.stylesheet = xsl;

     processor = template.createProcessor();
     processor.input = xml;
     processor.addParameter("param1", "someValue");
     processor.addParameter("param2", "someOtherValue");

processor.transform();

     document.write(processor.output);
  }

You then need to add the xsl:params as a top level elements in your
stylesheet to receive the parameters.  So in this case:

<xsl:stylesheet xmlns:xsl="http:.....
<xsl:param name="param1"/>
<xsl:param name="param2"/>

Notice the name must match the first parameter in addParameter().  You can
then access the parameter using the dollar sign - $param1.

If you are using msxml3 or lower, remember to alter the '.4.0' on the

ids.


cheers

andrew
