Pivot complex XML using Xquery

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">
<item sku="987654">
<sku>987654</sku>
<category-links>
<category-link name="abc" domain="WhiteStuff-DE-WebCategories" default = "0" hotdeal = "0"/>
<category-link name="def" domain="WhiteStuff-DE-WebCategories" default = "1" hotdeal = "0"/>
<category-link name="ghi" domain="WhiteStuff-DE-WebCategories" default = "0" hotdeal = "0"/>
</category-links>
<images>
<primary-view image-view="FF" />
<image-ref image-view="FD" image-type="w150" image-base-name="FD.jpg" domain="WhiteStuff" />
<image-ref image-view="FF" image-type="ORI" image-base-name="FF.jpg" domain="WhiteStuff" />
</images>
<variations>
<variation-attributes>
<variation-attribute name = "size">
<presentation-option>default</presentation-option>
<custom-attributes>
<custom-attribute name="displayName" dt:dt="string" xml:lang="en-US">Size</custom-attribute>
<custom-attribute name="productDetailUrl" xml:lang="de-DE" dt:dt="string">123.co.uk</custom-attribute>
</custom-attributes>
</variation-attribute>
<variation-attribute name = "colour">
<presentation-option>colorCode</presentation-option>
<presentation-product-attribute-name>rgbColour</presentation-product-attribute-name>
<custom-attributes>
<custom-attribute name="displayName" dt:dt="string" xml:lang="en-US">Colour</custom-attribute>
<custom-attribute name="productDetailUrl" xml:lang="de-DE" dt:dt="string">456.co.uk</custom-attribute>
</custom-attributes>
</variation-attribute>
</variation-attributes>
</variations>
</item>
</data>
'

This is my starting block:

;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);

It is not so clear how to distinguish between languages:

  • [productDetailUrl DE]
  • [productDetailUrl EN]

Other than that, please try the following solution. It will get you started.
