使用Xquery枢轴复杂XML

Question

是否有可能将以下xml转换为进入以下结果集，或者使结构尽可能接近它？它显然可以有多个项目与类似的数据，我刚刚削减了它，所以只有项目sku 987654是在文件中。

DECLARE @XML AS XML = '<data xsi:schemaLocation="http://www.intershop.com/xml/ns/enfinity/7.0/xcs/impex catalog.xsd http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt dt.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.intershop.com/xml/ns/enfinity/7.0/xcs/impex" xmlns:xml="http://www.w3.org/XML/1998/namespace" xmlns:dt="http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt" major="6" minor="1" family="enfinity" branch="enterprise" build="2.6.6-R-1.1.59.2-20210714.2">

这是我的起点：

;WITH XMLNAMESPACES 
(
    DEFAULT 'http://www.intershop.com/xml/ns/enfinity/7.0/xcs/impex',
    'http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt' as dt
)

SELECT n.value('@sku', 'nvarchar(max)') as [sku]

    --[category-link],
    --[FD image],
    --[FF image],
    --[productDetailUrl DE],
    --[productDetailUrl EN]

FROM @XML.nodes('/data/item') as x(n);

Answer 1

不太清楚如何区分语言：

• productDetailUrl DE
• productDetailUrl引擎

除此之外，请尝试以下解决方案。它会让你开始。
