RSS help

I have my rss feed working pefectly but I was wondering if I could limit
it to showing just the 5 most recently updated products.

heres how my rss is coded

xml.instruct!

xml.rss "version" => "2.0", "xmlns:dc" => "http://purl.org/dc/elements/
1.1/" do
  xml.channel do

   xml.title "FlashItem products"
   xml.link url_for :only_path => false, :controller =>
'products'
   xml.description "Items advertised on the FlashItems website"

    @products.each do |p|
     xml.item do
      xml.title(p.item_name)
      xml.link(url_for :only_path => false, :controller =>
'products',:action => 'show', :id => (p.id))
      xml.description(p.description)
      xml.guid(url_for :only_path => false, :controller => 'products',
:action => 'show', :id => (p.id))
      xml.pubDate(p.updated_at)
      xml.sellername(p.seller_name)
      xml.selleremail(p.seller_email)
     end
    end
  end
end

controller

def rss
      @products = Product.find(:all, :order=> "item_name")
      render :layout => false
      end

Not much to do with your rss, just add a :limit => 5 to your
Product.find and order it by updated_at.
