When I run that I get a pile of error messages after the first loop:-
   Use of uninitialized value in substr at /../Provider.pm
     line 1095, <DATA> chunk 1.


That could give you a clue as to whats happening....

Anyhow, you are passing a filehandle to the process() method,
however after the first time through the "file" has been consumed,
but you are not reseting or otherwise dealing with that, so every
loop after the first has an empty template.

You would therefore expect that the output of the second and subsequent
runs would be nothing, except process() is *appending* to the string
reference you passed....

I guess that should help you sort the problem.
