    var xmlDom=new ActiveXObject("Microsoft.XMLDOM") 
　　xmlDom.loadXML(xml) 
    alert(xmlDom);
    $.ajax({

          data:xmlDom,
          beforeSend:function(){},
          success:function(xmlDom){
             rData=unescape(xmlDom);
             
          },
          error:function(oXmlHttpReq, textStatus, errorThrown){
             alert("編輯裝置參數失敗!"+textStatus);
          }

}
