Ниже приведен вывод, который я хотел бы получить, но продолжаю получать ошибки XML форматирования. Также только Сообщение является родительским. Хотелось бы вывод, как показано ниже. Я использую переменные для заполнения пары тегов, а CollectSample - это поле stati c. 

 <Message>
    <TransactionType><![CDATA[CollectSamplingData]]></TransactionType>
    <TransactionID><![CDATA[0CA4E46F-5143-498C-B1AC-F990FF70462E]]></TransactionID>
    <TransactionDate><![CDATA[2020-01-10T14:20:30-05:00]]></TransactionDate>
    <CName><![CDATA[Name]]></CName>
    <MakeCar><![CDATA[Make]]></MakeCar>
    <MakeModel><![CDATA[Model]]></MakeModel>
    <DataValue><![CDATA[Price]]></DataValue>
    <MakeType><![CDATA[Type]]></MakeType>
  </Message>

declare @RepCar table
(
[Name] varchar(10),
[Make] varchar(10),
[Model] varchar(10),
[Price]  money,
[Type] varchar(10)
);

insert into @RepCar
(
Name, Make, Model, Price, Type
)
values
('Car1', 'Make1', 'Model1', 100, 'Type1'),
('Car2', 'Make2', 'Model2', 200, 'Type2'),
('Car3', 'Make3', 'Model3', 300, 'Type3');



DECLARE @TransactionId NVARCHAR(100)
DECLARE @TransactionDateTime DATETIME
--Setting Variable
SET @TransactionId= (SELECT CONVERT(VARCHAR, CURRENT_TRANSACTION_ID()))
SET @TransactionDateTime= GETDATE()

/*

AttributeName
Provides the name of the attribute to construct in the specified ElementName. This is the behavior if Directive is not specified.

!!!! If Directive is specified and it is xml, cdata, or element, this value is used to construct an element child of ElementName, and the column value is added to it.!!!!
