FAP is a ruby gem build on top of the excellent Nokogiri, to turn boring XML, or HTML documents into yummy ruby objects. Right now, it only support using Nokogiri’s XPath selectors, and simple “relations” between a document nodes, though this will hopefully get better.

FAP’s ideas are loosely connected to tools built by some adventurous fellas at AF83, who still do PHP things to their brains. Some credits should go to them, and to the horrid weather that kept me locked inside last week-end.

And yes, I know it’s a stupid name. But I’m sure you can come up with a decent acronym. :)

class Atom < FAP::Paw
  string :title,   :xpath => '//feed/title'
  uri    :url,     :xpath => '//feed/link[@rel="self"]', :get => :href
  date   :updated, :xpath => '//feed/updated'

  has_many :articles, :class => 'Article', :xpath => '//feed/entry'
end

class Article < FAP::Paw
  string :title # It is assumed here, that you want a string mapped on a <title> element
  uri    :url, :xpath => 'link[@rel="alternate"]', :get => :href    # Fetch the :href attribute
  string :content
  date   :updated_at, :xpath => 'updated'

  belongs_to :atom, :class => 'Atom'
end

atom = Atom.new open("http://search.twitter.com/search.atom?q=ruby")
atom.articles.each do |article|
  puts "#{article.title}: #{article.url}"
end
