Have a look at the package gtk-type_conversion.ads, which you need to "with" 
in your project for the above to work.
Generally speaking, it is probably better and more efficient to store a direct 
instance of your widget into another one rather than access it by name, if 
you can:

    type My_Window_Record is new Gtk_Window_Record with record
        XML : Gtk_Text_View;
    end record;
