[erlang-questions] string:strip/3 don't work right striping

[Gustav Simonsson]

string:strip(string:to_lower("....Hello...."), both, $.).
will evaluate to "hello". The reason you received dots in your
shell might be because you print out the raw Data after you print
out ReParseData, without anything printed between.

Hello,

I receive data by socket in tcp:

receive_loop(Socket) ->
    case gen_tcp:recv(Socket, 0) of
	 {ok, Data} ->
	    ReParseData = string:strip(string:to_lower(Data), both, $.),
	    io:format(ReParseData, []),
	    case ReParseData of
		"quit\r\n" ->
	          gen_tcp:send(Socket, "quit \r\n"),
		  gen_tcp:close(Socket);
	        _ ->
		  io:format(Data, []),
		  receive_loop(Socket)
	     end;
	 {error, closed} ->
	    ok
    end.

if I send .........................Hello
......................................
I got in shell:
>Hello ......................................

How can i correctly delete space from left and right in stirng?

Thank you.
