To call xslt scripts developed inside ExtendScript

Here is a general purpose function that you can use to invoke an XSLT transform:

function runTransformation (transform) {
    
    /* transform is a JavaScript object:
       .xml = absolute path to the file to transform
       .xsl = absolute path to the XSL stylesheet
       .pro = XSLT processor (SAXON)
       .out = absolute path to the transformed file.
       .console = true to show the Console,
           false to suppress the Console
       .params = an array of objects containing
           name/value pairs (optional)
    */
    
    var cmd, count, i, result;
    
    // Create the command string.
    cmd = 'XSLTRunTrScenario ' +  
        '-file \"' + transform.xml + '\" ' +
        '-xslfilepath \"' + transform.xsl + '\" ' +
        '-processor \"' + transform.pro + '\" ' +
        '-outputfilepath \"' + transform.out + '\"';
        
    // See if Console messages should be displayed.
    if (transform.console === false) {
        cmd += " -dontusefmconsole";
    }

    // Add any parameters to the command line.
    count = transform.params.length;
    for (i = 0; i < count; i += 1) {
        cmd += ' -sparam ' + transform.params[i].name + ' "' + 
            transform.params[i].value + '"';
    }

    // Invoke the transform.
    result = CallClient ("FmXSLT", cmd);
}
