問題描述

限時送ChatGPT賬號..

是否可以將以下 xml 轉(zhuǎn)換為以下結(jié)果集，或讓結(jié)構(gòu)盡可能接近它?它顯然可以有超過 1 個具有相似數(shù)據(jù)的項目，我剛剛對其進行了修剪，因此文件中只有項目 sku 987654.

Is it possible to pivot the following xml into the following result set, or get the structure as close to it as possible? It can obviously have more than 1 item with similar data, I have just trimmed it down so only item sku 987654 is in the file.

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">

<category-link name="abc" domain="WhiteStuff-DE-WebCategories" default = "0" hotdeal = "0"/>
<category-link name="def" domain="WhiteStuff-DE-WebCategories" default = "1" hotdeal = "0"/>

</custom-attributes>
</variation-attribute>
</variation-attributes>
</variations>
</item>
</data>
'

這是我的起點:

;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);

推薦答案

不太清楚如何區(qū)分語言:

It is not so clear how to distinguish between languages:

[productDetailUrl DE]
[productDetailUrl EN]

除此之外，請嘗試以下解決方案.它會讓你開始.
