How to load and unload same SWF with different xmlFilePath?

Question

I have a slideshow on my homepage and try to load and unload same instance with different xmlFilePath based on language on the same page.
var flashvars = {
        xmlFilePath: escape("http://www.bodto.com.tr/kik.aspx"),
        xmlFileType: "OPML",
        lang: swfobject.getQueryParamValue("lang")    
        //initialURL: escape(document.location)   
      var params = {
        bgcolor: "#000000",  
        allowfullscreen: "true",
        wmode:"transparent",
        allowScriptAccess: "always"
      var attributes = {}
          swfobject.embedSWF("/swf/slideshowpro.swf", "flashcontent", "550", "400", "10.0.0", false, flashvars, params, attributes);
Actionscript3
var langPath = root.LoaderInfo.parameters["xmlFilePath"]+root.LoaderInfo.parameters["lang"];
my_ssp.xmlFilePath = langPath;
var fileType = root.LoaderInfo.parameters["xmlFileType"];
my_ssp.xmlFileType = fileType;
Based on above informations, how could I achieve it?

Answer 1

Suddenly that code in the following gives me some error
var langPath = root.LoaderInfo.parameters["xmlFilePath"]+root.LoaderInfo.parameters["lang"];
my_ssp.xmlFilePath = langPath;
var fileType = root.LoaderInfo.parameters["xmlFileType"];
my_ssp.xmlFileType = fileType;
Access of possibly undefined property LoaderInfo through a reference with static type flash.display:DisplayObject.
The only code snippet works is
var paramObj:Object = LoaderInfo(this.root.loaderInfo).parameters;
for (var param in paramObj) {
   if (param == "xmlFilePath") {
      my_ssp.xmlFilePath = paramObj[param];
   if (param == "xmlFileType") {
      my_ssp.xmlFileType = paramObj[param];
