T-SQL无法使用多个嵌套命名空间查询XML，也无法查询唯一ID

Question

我需要从xml文件创建一个查询，该文件包含4个名称空间，但没有一个具有唯一的id。例如。的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"

如果我从文档中删除所有名称空间（通过Visual Studio），我可以很好地检索数据，但我需要保持名称空间不变。

<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

您已经定义了命名空间 - 但是您永远不会在XPath中使用它们！此外，我强烈建议使用内置的XQuery功能而不是传统的OPENXML方法。

试试这个选择语句：

;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：

当你在问题中提供的XML，以及这里的代码，你得到这个输出：

所以，要么您没有真正使用您提供的示例XML，要么您正在使用不同的代码......
