Yarss – Yet Another RSS Feed Normalizer.

Parse and access RSS/RDF/Atom feeds with a uniform interface. Yarss uses MutliXml behind the scenes so you may want to drop in your favourite XML parser.

For MRI users Ox is highly recommended as it is the fastest XML parser I know of. JRuby users should probably use Nokogiri.

Usage

# Parse from a String (raw XML), a Pathname, or an IO:
feed = Yarss.new('<xml string>...')
feed = Yarss.new(Pathname.new('path/to/feed.rss'))
feed = Yarss.new(File.open('path/to/feed.rss', 'rb'))

# Parse using IO-like, needs to respond to #read:
feed = Yarss.from_io(Pathname.new('path/to/feed.rss'))
feed = Yarss.from_io(File.open('path/to/feed.rss', 'rb'))

# Parse from a file path:
feed = Yarss.from_file('path/to/feed.rss')

# Parse from a string:
feed = Yarss.from_string('<xml string>...')

# Access feed attributes:
feed.title       # => "Foo's bars"
feed.link        # => 'http://foo.bar/'
feed.description # => 'Bars everywhere!'

# Access feed items:
feed.items.each do |item|
  item.id         # => 'id'
  item.title      # => 'Hello!'
  item.updated_at # => #<DateTIme ...>
  item.link       # => 'http://foo.bar/1'
  item.author     # => 'Joe'
  item.content    # => '<p>Hi!</p>'
end

Installation

Add this line to your application's Gemfile:

gem 'yarss'

# To increase performance, add one of these gems:
# gem 'ox'       # MRI compatible.
# gem 'nokogiri' # MRI and JRuby compatible.
# gem 'oga'      # MRI, JRuby, Rubinius compatible.

And then execute:

$ bundle

Or install it yourself as:

$ gem install yarss
