我能够将SQL引入并作为XML对象读取。目前，我使用SSIS将XML文本放在一个字符串中。

在SSIS中读取文件后，它将它带入我的数据库，进入如下的临时表：

Staging Table

现在可以将文件放入我的临时表中，我想使用触发器将它们解析为特定的列。请注意，XML字符串是UTF-8。此数据来自Dell硬件清单XML文件。 他们的文档在此图中概述了他们的XML模式：

Diagram

我需要将XML数据转换为模仿该图的列格式。所以标题是：

CIM | Messgae | Classname | InstanceID | PropertyName |价值| DisplayValue

这些列将在XML中包含它们各自的数据

另外，正如我所提到的，它是utf-8格式。要在SQL中将其作为XML对象读取，我使用以下代码：

declare @XML xml
set @XML = (SELECT Top 1 REPLACE([XML], 'utf-8', 'utf-16')FROM [StagingTable])

SELECT @XML

此外，我有多个INSTANCENAME实例，其中有更多集INSTANCE，PROPERTY，VALUE，DISPLAYVALUE等。

以下是根据Dell文档的XML架构：
