Just do something like this:

for (i = 0...items) {
   xml = glade_xml_new (...);

   if ((widgets[i] = glade_xml_get_widget (...)) == NULL)
       error ();

   /* Here you need to deal with the limitation of having to use a
GtkWindow toplevel,
    * so assuming its a normal widget you'll have to do something like this:
    */
   toplevel = glade_xml_get_widget (...);
   g_object_ref (widgets[i]);
   gtk_container_remove (widget from the toplevel);
   gtk_widget_destroy (the toplevel);

   /* and always dont forget to not leek the GladeXML */
   g_object_unref (xml);
}

Note that in the GtkBuilder api you can do exactly the same.
