out.println(" <xmllist>");
Powertype mes = (Powertype) li.get(i);
//System.out.println(mes.getId());
out.println(" <powertypeid>" + mes.getId()+ " </powertypeid>");
out.println(" <powertypename>" + mes.getVPowerTypeName()+ " </powertypename>");
out.println(" <powertypeorderid>" + mes.getIPowerOrderId()+ " </powertypeorderid>");
out.println(" <powertypecontent> </power
