SQL Server XML查询：查询多个同名子元素

在上一个问题中，我想知道如何使用 SQL 来JOIN基于标识符的不同 XML 元素。如您所见，我获得了几个不错的解决方案here https://stackoverflow.com/questions/60511464/sql-server-xml-processing-join-different-nodes-based-on-id/.

现在我正在根据我的实际数据调整这个解决方案。不幸的是，我偶然发现了一个新的障碍，该障碍在我在链接问题中提供的最小可行示例中不存在。在我的实际数据中，我还有几个同名的子元素。查看元素<subElement>在以下示例数据中。

<xml>
    <dataSetData>
        <text>ABC</text>
    </dataSetData>
    <generalData>
        <id>123</id>
        <text>text data</text>
        <subElement>
            <subData>sub example data AAA</subData>
        </subElement>
        <subElement>
            <subData>sub example data BBB</subData>
        </subElement>
    </generalData>
    <generalData>
        <id>456</id>
        <text>text data 2</text>
        <subElement>
            <subData>sub example data CCC</subData>
        </subElement>
    </generalData>
    <specialData>
        <id>123</id>
        <text>special data text</text>
    </specialData>
    <specialData>
        <id>456</id>
        <text>special data text 2</text>
    </specialData>
</xml>

预期结果应如下所示。

DataSetData | GeneralDataID | GeneralDataText | subData              | SpecialDataTest
ABC         | 123           | text data       | sub example data AAA | special data text
ABC         | 123           | text data       | sub example data BBB | special data text
ABC         | 456           | text data  2    | sub example data CCC | special data text 2

目前的解决方案（不考虑<subElement>数据）如下（取自here https://stackoverflow.com/a/60523502/973158):

SELECT TheXml.value('(/xml/dataSetData/text/text())[1]', 'VARCHAR(20)') AS DataSetData
     ,B.*
    , sp.value('(id/text())[1]', 'INT') AS SpecialDataID 
    , sp.value('(text/text())[1]', 'VARCHAR(30)') AS SpecialDataTest
INTO dbo.TestResult4
FROM dbo.TestXml
CROSS APPLY TheXml.nodes('/xml/generalData') AS A(g)
CROSS APPLY(SELECT g.value('(id/text())[1]', 'INT') AS GeneralDataID 
                 , g.value('(text/text())[1]', 'VARCHAR(30)') AS GeneralDataText) B
OUTER APPLY TheXml.nodes('/xml/specialData[id=sql:column("B.GeneralDataID")]') AS special(sp);

好吧，这很简单……

SELECT TheXml.value('(/xml/dataSetData/text/text())[1]', 'VARCHAR(20)') AS DataSetData
    , B.*
    , se.value('(subData/text())[1]','varchar(100)') AS SubData 
    , sp.value('(id/text())[1]', 'INT') AS SpecialDataID 
    , sp.value('(text/text())[1]', 'VARCHAR(30)') AS SpecialDataTest
FROM dbo.TestXml
CROSS APPLY TheXml.nodes('/xml/generalData') AS A(g)
CROSS APPLY(SELECT g.value('(id/text())[1]', 'INT') AS GeneralDataID 
                 , g.value('(text/text())[1]', 'VARCHAR(30)') AS GeneralDataText) B
OUTER APPLY A.g.nodes('subElement') C(se)
OUTER APPLY TheXml.nodes('/xml/specialData[id=sql:column("B.GeneralDataID")]') AS D(sp);
