T-SQL无法查询具有多个嵌套名称空间且没有唯一ID的XML

我需要从一个包含4个名称空间的xml文件中创建一个查询，但是它们都没有唯一的ID。例如。 xmlns：fb

我在下面列出了它们：

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"

如果我从文档中剥离了​​所有名称空间（通过Visual Studio），则可以很好地检索数据，但是我需要保持名称空间完整。

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

这是我尝试过的T-SQL代码：

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

您已经定义了名称空间-但您从未在XPath中使用！另外，我强烈建议在内置的OPENXML方法之上使用内置的XQuery功能。

尝试以下选择语句：

;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)

这应该从XML字符串中获取所需的数据。

更新：

当您在问题中提供的XML以及此处的代码时，您确实会得到以下输出：

因此，您可能不是真的在使用提供的示例XML，或者您正在使用其他代码……
