This is more a regex problem than an erlang problem IMHO. You could do
it like with this regex:
"<\\(.+\\):\\(.+\\)[(]\\(.+\\)(,[\s]*\\([^ ]+\\))*[)]>"
                                        ====

Here I've used anything but space ( [^ ] ) but ideally you would like to
have anything but \s. See the documentation of this particular regex
language to have the expected behaviour.
