Hi,
I would not do the export of the frame within an XML rule.
Without the export InDesign will create more than two frames.
function sample(){
    this.name = "sample";
    this.xpath = '//*[@font="Medicine Symbols 1"]';
    this.apply = function (myElement, myRuleProcessor){
     with(myElement){
      var myframe = myDoc.pages[0].textFrames.add();
        myElement.placeXML(myframe);
        myframe.fit(FitOptions.FRAME_TO_CONTENT);
        //myframe.select();
        //var imageName = myElement.xmlAttributes.item('id').value''       
        //$.writeln (filepath = myFolder+"/"+imageName+".jpg");
        //myframe.exportFile(ExportFormat.JPG, new File(filepath), false);
thanks Stefan
