A declarative SAX parsing library backed by Nokogiri
require 'sax-machine' # Class for parsing an atom entry out of a feedburner atom feed class AtomEntry include SAXMachine element :title # the :as argument makes this available through atom_entry.author instead of .name element :name, :as => :author element "feedburner:origLink", :as => :url element :summary element :content element :published end # Class for parsing Atom feeds class Atom include SAXMachine element :title # the :with argument means that you only match a link tag that has an attribute of :type => "text/html" # the :value argument means that instead of setting the value to the text between the tag, # it sets it to the attribute value of :href element :link, :value => :href, :as => :url, :with => {:type => "text/html"} element :link, :value => :href, :as => :feed_url, :with => {:type => "application/atom+xml"} elements :entry, :as => :entries, :class => AtomEntry end # you can then parse like this feed = Atom.parse(xml_text) # then you're ready to rock feed.title # => whatever the title of the blog is feed.url # => the main url of the blog feed.feed_url # => goes to the feedburner feed feed.entries.first.title # => title of the first entry feed.entries.first.author # => the author of the first entry feed.entries.first.url # => the permalink on the blog for this entry # etc ... # you can also use the elements method without specifying a class like so class SomeServiceResponse elements :message, :as => :messages end response = SomeServiceResponse.parse("<response><message>hi</message><message>world</message></response>") response.messages.first # => "hi" response.messages.last # => "world"
