<SCRIPT>
function fnFindSpecified(){
   var oAttributes=oList.attributes;
   alert(oAttributes(0).nodeName);
   for(var i=0;i<oAttributes.length;i++){
      var oNode=document.createElement("LI");
      var oNodeValue=document.createTextNode(i + " "
                     + oAttributes(i).nodeName + " = "
                     + oAttributes(i).nodeValue);
      oList.appendChild(oNode);
      oNode.appendChild(oNodeValue);
      if(oAttributes(i).nodeValue!=null){
         alert(oAttributes(i).nodeName
         + " specified: " + oAttributes(i).specified);
      }
   }
}
