Sql server SQL Server XML查询：查询具有相同名称的多个子元素

在前面的一个问题中，我想知道如何使用SQL根据标识符连接不同的XML元素。正如你所看到的，我得到了几个很好的解决方案

现在，我正在根据实际数据调整此解决方案。不幸的是，我偶然发现了一个新的障碍，这个障碍在我在相关问题中提供的最低可行的例子中并不存在。在我的实际数据中，我还有几个同名的子元素。请参见以下示例数据中的元素

<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>

当前解决方案（不考虑

数据）如下所示（摘自）：

好吧，这很直截了当
