Sql server 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id。例如xmlns:fb

我把它们列在下面：

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所有名称空间（通过VisualStudio），我可以很好地检索数据，但我需要保持名称空间完整

您已经定义了名称空间，但在XPath中从未使用它们！另外，我强烈建议使用内置的XQuery功能，而不是传统的

OPENXML

方法

请尝试此select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：

当您输入问题中提供的XML以及此处的代码时，确实会得到以下输出：

因此，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……

感谢select语句，但它不返回任何数据。我在这个链接中提供了一个XML结构的屏幕截图——在T-SQL中，“root”似乎是一个保留字，但更改它也不会返回任何数据。@Walkdog：我提供的代码确实适用于您在问题中显示的XML。查看我的更新。因此，我猜您正在尝试此代码的XML与您在此处发布的示例的结构（尤其是XML名称空间）不同。我很抱歉，您是对的。我试图使用已删除名称空间的XML运行该语句。该脚本在原始文件上运行得非常好。非常感谢。
