Question

我有xml如下所示，我已经设法一次获得了physicalAddress的一个变量，但我想获取子注释中的所有现有记录（如果存在），否则我有重复的问题。

期望的结果是将所有子记录放在一列中以反映每个记录的详细信息，因此如果有5个地址，我将在每行中有5个地址部分不同的记录

感谢您的帮助。

谢谢

使用的XML：

使用SELECT：

SELECT id, t.r.value('
                 declare namespace C1="mypath";
                 declare namespace CAM1="MMMMMMM";
                 declare namespace C2="ZZZZZZZZZZZZZZ";
                 declare namespace CAM2="OOOOO";
                       (.)', 'varchar(50)') as address1
FROM
[XXX_SH_SOAService_formattedXML] OUTER APPLY
[XML].nodes('
                 declare namespace C1="mypath";
                 declare namespace CAM1="MMMMMMM";
                 declare namespace C2="ZZZZZZZZZZZZZZ";
                 declare namespace CAM2="OOOOO";

 /C1:PostData/C1:data/CAM1:CurrentEBO/ 
 CAM1:Person/C2:PhysicalAddresses/C2:PhysicalAddress/CAM2:Address1') t(r)

如果这个XML的构建在你的控制之下你应该尝试改变这些命名空间的混乱......特别难以看出一个元素在新定义的默认命名空间中反复使用哪个ns

在大多数情况下，最好是尽可能具体。但是在这里我建议通过在任何地方使用通配符来忽略名称空间：

SELECT t.ID ,pers.value(N'(*:PersonName/*:FirstName/text())[1]',N'nvarchar(200)') AS Person_FirstName --more of Person ,addr.value(N'(*:Identification/*:AddressNumber/text())[1]',N'uniqueidentifier') AS Address_Number --AddressUsage would need one more `.nodes()`, as it is 1:n within each address ,addr.value(N'(*:EffectiveDates/*:StartDateTime/text())[1]',N'datetime2') AS Address_StartDateTime ,addr.value(N'(*:Address1/text())[1]',N'nvarchar(max)') AS Address_Address1 ,addr.value(N'(*:Address2/text())[1]',N'nvarchar(max)') AS Address_Address2 ,addr.value(N'(*:Address3/text())[1]',N'nvarchar(max)') AS Address_Address3 ,addr.value(N'(*:City/text())[1]',N'nvarchar(max)') AS Address_City --more of the same FROM @tbl AS t OUTER APPLY t.YourXml.nodes(N'/*:PostData/*:data/*:CurrentEBO/*:Person') A(pers) OUTER APPLY pers.nodes(N'*:PhysicalAddresses/*:PhysicalAddress') B(addr);

我不赞成这个：

我会有5条记录，每行的地址部分不同

但是上面应该指明你的方式......

在TSQL中使用命名空间解析XML - 子详细信息
