  # GET /items.xml
  def index
    @items = Item.all

    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @items }
    end
  end
# ----- CUT ------
  # DELETE /items/1
  # DELETE /items/1.xml
  def destroy
    @item = Item.find(params[:id])
    @item.destroy

    respond_to do |format|
      format.html { redirect_to(items_url) }
