The outdated approach with FROM OPENXML might be an option here. Check this answer.
At this link you'll find a function John Cappelletti posted from time to time, which will shred any XML (credits below the function's code).
But I'm not sure, what you are really trying to achieve... Why do you need the path? If you are interested in the values of all target nodes you might do something like this (deep search with // does not need the exact XPath)
SELECT t.value(N'(text())[1]','nvarchar(max)')
FROM @xml.nodes('//target') AS A(t);
If you really need all and everything you can check this:
CREATE FUNCTION [dbo].[udf-XML-Hier](@XML xml)
