Generate complex XML with T-SQL syntax - sql-server

Question

I am trying to build a query that would return more or less complex XML structure. This is expected output I would like to have:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>
<a:Action s:mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
<a:MessageID>urn:uuid: some_messageID</a:MessageID>
<a:ReplyTo>
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
<a:To s:mustUnderstand="1">ServiceURL</a:To>
</s:Header>
<s:Body>
<HereRouteMatchExtension xmlns="http://tempuri.org/">
<vehicleTrace xmlns:b="http://schemas.datacontract.org/2004/07/FMCommonTypes.WCF" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
<s:Latitude>2</s:Latitude>
<s:Longitude>2</s:Longitude>
<s:PositionGuid>577AF773-C7A8-4D65-82DA-37A15CC7611D</s:PositionGuid>
</vehicleTrace>
</HereRouteMatchExtension>
</s:Body>
</s:Envelope>
I am using following code:
CREATE TABLE #test
(
Latitude INT,
Longitude INT,
PositionGuid UNIQUEIDENTIFIER
)
INSERT INTO #test VALUES (1,1,NEWID())
INSERT INTO #test VALUES (2,2,NEWID())
WITH XMLNAMESPACES ('http://www.w3.org/2003/05/soap-envelope' AS s, 'http://www.w3.org/2005/08/addressing' AS a)
SELECT
( SELECT '1' AS [a:Action/#mustUnderstand],
'http://tempuri.org/IGeocodeService/HereRouteMatchExtension' AS [a:Action]
FOR XML PATH (''), TYPE
),
'urn:uuid: some_messageID' AS 'a:MessageID',
( SELECT 'http://www.w3.org/2005/08/addressing/anonymous' AS [a:Address]
FOR XML PATH ('a:ReplyTo'), TYPE
),
( SELECT '1' AS [a:To/#mustUnderstand],
'ServiceURL' AS [a:To]
FOR XML PATH (''), TYPE
),
( SELECT '1' AS [a:Action/#mustUnderstand]
FOR XML PATH (''), TYPE
),
(SELECT Latitude AS 's:Latitude',
Longitude AS 's:Longitude',
PositionGuid AS 's:PositionGuid'
FROM #test
FOR XML PATH ('s:Body'), TYPE
)
FOR XML RAW ('s:Header'), ELEMENTS, ROOT('s:Envelope')
There are 2 problems in the code i generated:
1) reference URLS are in every sub-section and I would like to have just once;
2) Body tag is inside the header and it is supposed to go straight after it...
How can I achieve that? This is the result I am getting:
<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>
<a:Action xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
<a:MessageID>urn:uuid: some_messageID</a:MessageID>
<a:ReplyTo xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
<a:To xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1">ServiceURL</a:To>
<a:Action xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope" mustUnderstand="1" />
<s:Body xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Latitude>1</s:Latitude>
<s:Longitude>1</s:Longitude>
<s:PositionGuid>34BD8E91-8567-4D58-A18E-61C3FBBF5C8F</s:PositionGuid>
</s:Body>
</s:Header>
</s:Envelope>

Answer 1

Try that
DECLARE #test TABLE
(
Latitude INT,
Longitude INT,
PositionGuid UNIQUEIDENTIFIER
)
INSERT INTO #test VALUES (1,1,NEWID());
INSERT INTO #test VALUES (2,2,NEWID());
WITH XMLNAMESPACES ('http://www.w3.org/2003/05/soap-envelope' AS s, 'http://www.w3.org/2005/08/addressing' AS a)
SELECT
1 AS [s:Envelope/s:Header/a:Action/#s:mustUnderstand],
'http://tempuri.org/IGeocodeService/HereRouteMatchExtension' AS [s:Envelope/s:Header/a:Action],
'urn:uuid: some_messageID' AS [s:Envelope/s:Header/a:MessageID],
'http://www.w3.org/2005/08/addressing/anonymous' [s:Envelope/s:Header/a:ReplyTo/a:Address],
1 as [s:Envelope/s:Header/To/#s:mustUnderstand],
'ServiceURL' as [s:Envelope/s:Header/To],
Latitude as [s:Envelope/s:Body/s:Latitude],
Longitude as [s:Envelope/s:Body/s:Longitude],
PositionGuid as [s:Envelope/s:Body/s:PositionGuid]
FROM #test
FOR XML PATH('')
This way you produce two Envelope elements one for each row of the #table.
Edit:
I could not find a way to remove extra namespaces from child elements when generated with TYPE in a subquery with FOR XML PATH.
I came up with this solution which does not fully satisfy me:
DECLARE #test TABLE
(
Latitude INT,
Longitude INT,
PositionGuid UNIQUEIDENTIFIER,
x xml
)
DECLARE #x xml =
'<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
<s:Header>
<a:Action s:mustUnderstand="1">http://tempuri.org/IGeocodeService/HereRouteMatchExtension</a:Action>
<a:MessageID>urn:uuid: some_messageID</a:MessageID>
<a:ReplyTo>
<a:Address>http://www.w3.org/2005/08/addressing/anonymous</a:Address>
</a:ReplyTo>
<a:To s:mustUnderstand="1">ServiceURL</a:To>
</s:Header>
<s:Body>
<HereRouteMatchExtension xmlns="http://tempuri.org/">

</vehicleTrace>
</HereRouteMatchExtension>
</s:Body>
</s:Envelope>'
INSERT INTO #test VALUES (10,10,NEWID(),#x);
INSERT INTO #test VALUES (20,20,NEWID(),#x);
UPDATE #test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:Latitude/text())[1] with sql:column("Latitude")')
UPDATE #test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:Longitude/text())[1] with sql:column("Longitude")')
UPDATE #test
SET x.modify('declare namespace s="http://www.w3.org/2003/05/soap-envelope";declare default element namespace "http://tempuri.org/";
replace value of (/s:Envelope/s:Body/HereRouteMatchExtension/vehicleTrace/s:PositionGuid/text())[1] with sql:column("PositionGuid")')
SELECT * FROM #test
and all at once with an insert:
DECLARE #test TABLE
(
Latitude INT,
Longitude INT,
PositionGuid UNIQUEIDENTIFIER,
x xml
)
DECLARE #x xml =
'<s:Envelope xmlns:a="http://www.w3.org/2005/08/addressing" xmlns:s="http://www.w3.org/2003/05/soap-envelope">
