@Bryan Bende, in the same way with routeOnAttribute processor, it is possible to regular expression.

In my dataflow listHDFS send flowfile to routeOnAttribute and i need check all subpath list above to route correctly all files in deleteHDFS.

At this moment for each directory I need to create an attribute to match a subpath of directory, so in my case I have created 35 attributes.

Can you use the "matches" function in expression language?

It should allow any regular expression:
