iOS開發後台請求報錯，幫忙看下XML格式哪裡有問題 急急急！！！大神們

報錯：Entity: line 1: parser error : Start tag expected, '<' not found
以下為請求XML，用的是ASIHTTPRequest請求架構，不知錯在何處
com.portal.android.ExecuteAndroidchangeState

請求資料代碼：
NSString *kvr = [NSString stringWithFormat:@"",@"",cell.shipNameTextField.text,cargoRemark,self.dockModel.t2,self.berthModel.t2,cargoType,self.cargoModel.t2,self.cargoModel.t1,cell.cargoWeightTextField.text,cell.billInfoTextField.text,@"",cell.delegateTextField.text,@"NODECL",appDelegate.userInfo.ORG_NAME,appDelegate.userInfo.ORG_ID,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,appDelegate.userInfo.USER_ID,appDelegate.userInfo.USER_NAME,self.personModel.t2];

• (void)sendRequest:(NSString )classPath metherName:(NSString )metherName kvrStr:(NSString )kvrStr andTag:(NSInteger) tag andUrl:(NSString )url
  {

  }];

  [request startAsynchronous];

由於把請求資料加密了，請求回調時處理資料未解密，所以導致了錯誤

格式沒錯哦，你用一個支援xml的ide開啟一下就可以知道有沒有語法錯誤。。。

請求資料是不是有錯誤？
能不能把你列印請求資料的代碼貼出來
