Exporting a xml document from sql 2008 - sql

Question

All
I have very little experience of xml, so please be gentle.
The situation is we use an application called dataswitch to take xml and process it into our ERP system via business objects.
The output I am trying to recreate is as follows from a sample xml document.
**<?xml version="1.0" encoding="Windows-1252" ?>
- <IssueDetails Language="05" CssStyle="" DecFormat="1" DateFormat="01" Role="01" Version="6.0.000">**
- <Item>
<Job>00000121</Job>
<NonStocked>N</NonStocked>
<Warehouse>RM</Warehouse>
<StockCode>BBMB100</StockCode>
<Line>00</Line>
<QuantityToIssue>1.000</QuantityToIssue>
</Item>
</IssueDetails>
So far I have worked on the For xml Path method to build my query and used the sp from Phil Factor to write the output
So far I have been successful creating an xml document which opens in the browser (many tries required!)
This is the output I have managed to create, please note the top lines are different
**<IssueDetails xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">**
- <Item>
<Job>00044816</Job>
<NonStocked>N</NonStocked>
<Warehouse>C2</Warehouse>
<StockCode>FG00707</StockCode>
<Line>00</Line>
<QuantityToIssue>400.000000000</QuantityToIssue>
</Item>
- <Item>
<Job>00044816</Job>
<NonStocked>N</NonStocked>
<Warehouse>C2</Warehouse>
<StockCode>FG00707</StockCode>
<Line>00</Line>
<QuantityToIssue>10.000000000</QuantityToIssue>
</Item>
</IssueDetails>
So my question is how do I get the top line in my output to be the same as the sample output?
My procedure is listed below
Declare
#XML_1 varchar (max),
#myXML varchar(max),
#myFile varchar (30),
#Path varchar (100)
set #XML_1=''
set #myFile ='MaterialIssuesTest.xml'
set #Path='D:\Temp\'
--Query database for materials
Set #XML_1 =#XML_1 + ( SELECT WJM.[Job]
,Case when WJM.[Warehouse]='**' then 'Y' else 'N' end as NonStocked
,WJM.[Warehouse]
,rtrim(LP.StockCode) as StockCode
,WJM.[Line]
,[UnitQtyReqd]*LP.LQtyComplete as QuantityToIssue
FROM [SysproCompanyR].[dbo].[WipJobAllMat] WJM
inner join CHC_Production.LabPostsAtMileOps LP On WJM.Job=LP.Job
Where WJM.Job in ('00044816')and (WJM.OperationOffset > LP.PrevOp
and WJM.OperationOffset<LP.LOperation)
FOR XML Path ('Item'),ROOT ('IssueDetails'), ELEMENTS XSINIL
)
set #myXML = LTRIM(rtrim(#XML_1))
--Debug print xml
Print #myXML
--Output xml to document
execute dbo.spWriteStringToFile #myXML, #Path, #myFile
GO

To get you first line, which is a child element of the main body you need to do a sub query like what I have done below. To get the attributes you need to name them with the # symbol, again in my example (formatting changes to aid me setting it out!):
SET #XML_1 =#XML_1 +
(
SELECT WJM.[Job],
(
SELECT '' AS '#Language',
'' AS '#CssStyle',
'' AS '#DecFormat',
'' AS '#DateFormat',
'' AS '#Role',
'' AS '#Version'
FROM YOURTABLENAME YTN
WHERE YTN.[SOMEFIELD] = WJM.[SOMEFIELD]
FOR XML PATH(''), TYPE
) AS 'IssueDetails'
,Case when WJM.[Warehouse]='**' then 'Y' else 'N' end as NonStocked
,WJM.[Warehouse]
,rtrim(LP.StockCode) as StockCode
,WJM.[Line]
,[UnitQtyReqd]*LP.LQtyComplete as QuantityToIssue
FROM [SysproCompanyR].[dbo].[WipJobAllMat] WJM
INNER JOIN CHC_Production.LabPostsAtMileOps LP ON WJM.Job = LP.Job
WHERE WJM.Job IN ('00044816') AND (WJM.OperationOffset > LP.PrevOp
AND WJM.OperationOffset<LP.LOperation)
FOR XML Path ('Item'), ROOT ('IssueDetails'), ELEMENTS XSINIL
)
I don't know where the data is coming from, so you will have to fill in the table name and the WHERE clause to join it to the data that you already have. That is assuming the data is a child of the data that you have already provided.
Bare in mind the syntax might not be quite correct as I am doing this from memory and there are several different variations to get this result.
