I used this, check it.

// Returns an array with the parts of "str" separated by "separator"
function Split(const str: string; const separator: string): array of string;
var
  i, n: integer;
  strline, strfield: string;
begin
  n:= Occurs(str, separator);
  SetLength(Result, n + 1);
  i := 0;
  strline:= str;
  repeat
    if Pos(separator, strline) > 0 then
    begin
      strfield:= Copy(strline, 1, Pos(separator, strline) - 1);
      strline:= Copy(strline, Pos(separator, strline) + 1, 
Length(strline) - pos(separator,strline));
    end
    else
    begin
      strfield:= strline;
      strline:= '';
    end;
    Result[i]:= strfield;
    Inc(i);
  until strline= '';
  if Result[High(Result)] = '' then SetLength(Result, Length(Result) -1);
end;
