How to not set a file/application association in OS/X?

In OS/X does anyone know how to not set a file/application association? I have both FileMaker and Final Cut Pro. If I export as XML from FileMaker, the OS sees it as a Final Cut Pro document and automatically opens Final Cut Pro and read the doc in Final Cut Pro.

Yes, I can use Get Info to change the association via “Always Open with…” but I want to set this to “None.” I’d rather XML docs (because of the variety of applications that may want to read them) have no association and let me manually choose the application I want to open the file in. Does anyone know how?


If you install RCDefaultApp, it offers the ability to remove all
applications associations from a particular type of file:
