我试过的是：

USE OPENXMLTesting
GO

DECLARE @XML AS XML, @hDoc AS INT, @SQL NVARCHAR (MAX)
SELECT @XML = XMLData FROM XMLwithOpenXML_2
EXEC sp_xml_preparedocument @hDoc OUTPUT, @XML


SELECT Category_ID, NameRecomendation
FROM OPENXML(@hDoc, 'GetCategorySpecificsResponse/Recomendations')
WITH 
(
Category_ID [varchar](100) 'Category_ID',
NameRecomendation [varchar](100) 'NameRecommendation'
)

EXEC sp_xml_removedocument @hDoc
GO

但我总是得到空桌子。由于我无法解析第一级，因此进一步获取是无稽之谈最终解决方案将包含列。

类别 ID、名称推荐/名称、
NameRecommendation/ValidationRules/SelectionMode
NameRecommendation/ValidationRules/UsageConstraint
NameRecommendation/ValidationRules/ValueType
NameRecommendation/ValueRecommendation/Value

【问题讨论】：

sp_xml_preparedocument 是一种真正解析 XML 的旧方法是 SQL Server； XQuery 至少从 SQL Server 2008（甚至可能是 2005 年）开始就可以使用。
您在这里的预期结果是什么？
@Larnu 首先是从 XML 获取所有可用的 CategoryID .. 最后的方法是获取有问题的 5 列
首先，您需要修复 XML；这是无效的。这就是为什么你所拥有的也不起作用。要解析 XML，它必须是有效的。例如，在上面，GetCategorySpecificsResponse 永远不会关闭。
@Larnu 抱歉。我只是复制了几个节点。文件超过 1.2 GB。我修复了丢失的标签

标签： sql-server xml tsql xquery sql-server-openxml

【解决方案1】：

没有预期的结果，这是一个猜测，但返回结果应该足以让您填补空白：

DECLARE @XML = {Your XML};

WITH XMLNAMESPACES(DEFAULT 'urn:ebay:apis:eBLBaseComponents')
SELECT GCSR.R.value('(CategoryID/text())[1]','int') AS CategoryID,
       R.NR.value('(Name/text())[1]','varchar(20)') AS [Name],
       R.NR.value('(ValidationRules/UsageConstraint/text())[1]','varchar(20)') AS UsageConstraint,
       NR.VR.value('(Value/text())[1]','varchar(20)') AS [Value]
FROM (VALUES(@XML))V(X)
     CROSS APPLY V.X.nodes('GetCategorySpecificsResponse/Recommendations')GCSR(R)
     CROSS APPLY GCSR.R.nodes('./NameRecommendation')R(NR)
     CROSS APPLY R.NR.nodes('./ValueRecommendation') NR(VR);
