我試過的是：

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

但我總是得到空桌子。 由於我無法解析第一級，因此進一步獲得最終解決方案將包含列是無稽之談。

  1. 類別 ID、名稱推薦/名稱、
  2. 名稱推薦/驗證規則/選擇模式
  3. 名稱推薦/驗證規則/使用約束
  4. 名稱推薦/驗證規則/值類型
  5. 名稱推薦/價值推薦/價值

沒有預期的結果，這是一個猜測，但返回結果應該足以讓您填補空白：

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);
