在这里，过时的方法FROM OPENXML可能是一个选择。检查此答案。

在此链接中，您会发现一个不时发布的功能John
Cappelletti，该功能将切碎所有XML（该功能代码下方的功劳）。

但我不确定，您真正想要实现的目标…为什么需要这条路？如果您对所有目标节点的值感兴趣，则可以执行以下操作（使用进行深度搜索//不需要确切的XPath）

 SELECT t.value(N'(text())[1]','nvarchar(max)')
 FROM @xml.nodes('//target') AS A(t);

如果您真的需要 所有的一切 ，可以检查以下内容：

CREATE FUNCTION [dbo].[udf-XML-Hier](@XML xml)
