Using SSIS to extract a XML representation of table data to a file

Question

I\'m trying to use SSIS to extract XML representation of a query result set to a text file. My query is currently successfully extracting the exact XML output I need when I

Answer 1

Sorry to spoil, but there's an SSIS option for you: Export Column Transformation.

I defined an OLE DB query with

SELECT
    *
FROM
(
    SELECT * FROM dbo.spt_values FOR XML AUTO, ROOT('RootVal')
) D (xml_node)
CROSS APPLY
(
    SELECT 'C:\ssisdata\so_xmlExtract.xml'
) F (fileName)

This results in 1 row and 2 columns in the dataflow. I then attached the Export Column Transformation and wired it up with xml_node as Extract Column and fileName as the File Path Column

Mostly truncated results follow

<RootVal>
    <dbo.spt_values name="rpc" number="1" type="A  " status="0"/>
    <dbo.spt_values name="dist" number="8" type="A  " status="0"/>
    <dbo.spt_values name="deferred" number="8192" type="V  " low="0" high="1" status="0"/>
</RootVal>

Answer 2

BillInKC's answer is the best I've ever seen, but SQL can be simplified (no need for cross apply):

SELECT X.*, 'output.xml' AS filename
FROM (SELECT * FROM #t FOR XML PATH('item'), ROOT('itemList')) AS X (xml_node)

It will output the same structure:

xml_node                                           filename
-------------------------------------------------- ----------
<itemList><item><num>1000</num></item></itemlist>  output.xml
