Assuming you are asking about comparing XML columns/variables, you cannot. You will have to use one of the XQuery functions to extract the data (to one of the other data types) and then compare. You cannot cast to varchar/nvarchar and compare either. (You can, but the results won't be reliable).

you dont need to use IN while dealing with XML data. You can pass exist() function and pass outside variable/columns inside Xquery conditions.
