$i is not a list of strings, it is a list of "import rule return 
structures".  (And I'm not exactly sure what type name that is; 
you'll need to check the generated code.)  This is partly because 
rules are permitted to return multiple things.

So you'd need to change the code in the document rule to:

   foreach (someType t in $i) Console.Write("\n>>" + t.s);

(replacing someType with the actual return type of the import 
rule.)
