xslt transform in mozilla

Here is the sample code of xslt tranformation  used for IE browsers.
Uing xslt processor and using addobject and addparameter.
Want to know the best code for Mozilla for achieving the same.

thanks

var ClientXML = new ActiveXObject("Microsoft.XMLDOM.4.0") ;
    ClientXML.async = false;
    ClientXML.load("Books.xml");

var ClientXSL = new ActiveXObject("MSXML.FreeThreadedDOMDocument.4.0")
;
    ClientXSL.async = false ;
    ClientXSL.load("Books.xsl");

var xslTemplate=new ActiveXObject("Msxml2.XSLTemplate.4.0") ;
    xslTemplate.stylesheet=ClientXSL ;
    var xslProcessor=xslTemplate.createProcessor ;
    xslProcessor.input=ClientXML ;

     //Generic Class instance added as an object
    xslProcessor.addObject(FnObj, "urn:Functions" );

     //Adding Parameters to processor
   xslProcessor.addParameter("ParamName",ParamValue)

    xslProcessor.transform();
    document.write(xslProcessor.output);
