This tag allows you to delete a menu item from any menu you have previously defined. This tag is used by itself and does not need to appear within <menu> or <submenu> tags. You need to at least define the name attribute to have a valid <deletemenuitem> tag. This is an empty tag, so you can either use a forward-slash before the closing angled bracket (“/>”) or follow the tag immediately with a closing </deletemenuitem> tag. This tag has one attribute, which is required.
<deletemenuitem name="menu item path" />
Defines the "path" to the menu item that you are deleting. The "path" is made up of the menu name, followed by any submenu names, followed by the actual name of the menu item, all separated with the forward-slash, and looks like "menu name/submenu name/menu item name".
