Microsoft SQL XML Processing

I have an XML String that is stored in a SQL table as a XML field.  I need to be able to extract the following fields using TSQL.

Date
DeviceDate
UserName
FirstName
LastName
ResponseID
Job_Num value (in the Response nodes)

I have tried:
SELECT  
        x.XmlCol.value('(Response/Label)[3]','VARCHAR(100)') as xLable,
             x.XmlCol.value('(Response/Value)[3]','VARCHAR(100)') as xValue
FROM    gcREsponses b
            CROSS APPLY b.gcResponse_formXML.nodes('/CanvasResult/Submissions/Submission/Sections/Section/Screens/Screen/Responses') x(XmlCol)

Which works for that particular form, but I cannot always count on Job_Num being in the 3rd element.  It could change based on the form type being submitted.

Any help would be appreciated.

If you know specifically that it's Job_Num that you have to query, then you'll have an easier time grabbing the value directly with a filter, instead of doing a cross apply against everything and then targeting that node.

Also, you can specify all named children with "//name" instead of needing to specify the entire xpath, just less typing.  Depends of course on whether or not you'll have other nodes named that in other levels.

Give this a shot:

select 
	r.gcResponse_formXML.value('(CanvasResult/Submissions/Submission/Date)[1]', 'datetime') as DeviceDate,
	r.gcResponse_formXML.value('(CanvasResult/Submissions/Submission/UserName)[1]', 'varchar(100)') as UserName,
	r.gcResponse_formXML.value('(CanvasResult/Submissions/Submission/FirstName)[1]', 'varchar(100)') as FirstName,
	r.gcResponse_formXML.value('(CanvasResult/Submissions/Submission/LastName)[1]', 'varchar(100)') as LastName,
	r.gcResponse_formXML.value('(//Responses/Response[Label=''Job_Num'']/Value)[1]', 'varchar(100)') as Job_Num
from gcREsponses r

Use a XPath filter like .nodes('/[..]/Response[Label="Job_Num"]') . E.g.

DECLARE @Xml XML =  N'

Don't use '//' in production code, when you need it often. Cause it is much slower than a full XPath addressing the correct element. Also //tagName can retrieve elements from different branches and levels.
