T-SQL cannot query XML with multiple nested namespaces and no unique ID

Question

I need to create a query from an xml file that hcontains 4 namespaces but none of them have a unique id. eg. xmlns:fb

I have listed them below:

xmlns="http://xxx/pie/svc/frs/FindRegistration/2.0.0"
xmlns="http://xxx/pie/xsd/frs/FindRegistrationMessages/2.0.0"
xmlns="http://xxx/pie/xsd/common/CommonCoreElements/2.0.0"
xmlns="http://xxx/pie/xsd/frs/PractitionerRegistrationElements/2.0.0"

If I strip all the namespaces (through Visual Studio) from the document I can retrieve the data fine, but I need to keep the namespaces intact.

<FindRegistrationsResponse xmlns="http://xxx/pie/svc/frs/FindRegistration/2.0.0">

This is the T-SQL code that I've tried:

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)

SELECT @XML = XMLData FROM AHPRA_XML

EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML


;WITH XMLNAMESPACES('http://xxx/pie/svc/frs/FindRegistration/2.0.0',
                    'http://xxx/pie/xsd/frs/FindRegistrationMessages/2.0.0',
                    'http://xxx/pie/xsd/common/CommonCoreElements/2.0.0',
                    'http://xxx/pie/xsd/frs/PractitionerRegistrationElements/2.0.0')

SELECT DISTINCT  ProfessionNumber, NameTitle, GivenName, MiddleName, FamilyName, Gender

FROM OPENXML(@hDoc, 'FindRegistrationsResponse/ProfessionNumberReplay/Practitioner')
WITH 
(
ProfessionNumber [varchar](50) '../@ProfessionNumber',
NameTitle [varchar](20) 'PractitionerName/NameTitle',
GivenName  [varchar](100) 'PractitionerName/GivenName',
MiddleName  [varchar](100) 'PractitionerName/MiddleName',
FamilyName [varchar](100) 'PractitionerName/FamilyName',
Gender [varchar](10) 'Demographics/Gender'
)

EXEC sp_xml_removedocument @hDoc
GO

You've defined the namespaces - but you never use them in your XPath! Also, I'd strongly recommend to use the built-in XQuery capabilities over the legacy OPENXML approach.

Try this select statement:

;WITH XMLNAMESPACES('http://xxx/pie/svc/frs/FindRegistration/2.0.0' AS root, 
                    'http://xxx/pie/xsd/frs/FindRegistrationMessages/2.0.0' AS msg,
                    'http://xxx/pie/xsd/frs/PractitionerRegistrationElements/2.0.0' AS el)
    SELECT
        ProfessionNumber = XC.value('(../@ProfessionNumber)', 'varchar(50)'),
        NameTitle = XC.value('(el:PractitionerName/el:NameTitle)[1]', 'varchar(50)'),
        GivenName = XC.value('(el:PractitionerName/el:GivenName)[1]', 'varchar(50)'),
        MiddleName = XC.value('(el:PractitionerName/el:MiddleName)[1]', 'varchar(50)'),
        FamilyName = XC.value('(el:PractitionerName/el:FamilyName)[1]', 'varchar(50)'),
        Gender = XC.value('(el:Demographics/el:Gender)[1]', 'varchar(50)')
    FROM
        @XML.nodes('/root:FindRegistrationsResponse/msg:ProfessionNumberReplay/msg:Practitioner') AS XT(XC)

This should grab the desired data from the XML string.

Update:

when you the XML you provided in the question, and this code here, you do get this output:

So either you're not really working with the sample XML you've provided, or you are using different code......
