A solution using the Iterate routine:

    procedure Do_Something (P : X_t.Cursor) is
       E : constant Item_T := Element (P);
    begin
       ...
    end Do_Something;

    X.Iterate (Do_Something'Access);

Another solution would be to loop using a cursor, something like:

    P : X_t.Cursor := X.First;

    while Has_Element (P) loop
       Do_Something (P);
       Next (P);
       --  With this loop it is possible to exit before the end
       --  exit when <some_condition>;
    end loop;

Both example have not been compiled, so could have some syntax error but 
you get the idea.

Pascal.
