Feedjira

Feedjira is a Ruby library designed to parse feeds.

Add this line to your application's Gemfile:

gem "feedjira"

An example of parsing a feed with Feedjira:

xml = HTTParty.get(url).body
feed = Feedjira.parse(xml)
feed.entries.first.title
# => "Announcing version 3.0"

If you have the XML and just want to provide a parser class for one parse, you can specify that using parse with the parser option:

Feedjira.parse(xml, parser: MyAwesomeParser)

# Add the generator attribute to all feed types
Feedjira::Feed.add_common_feed_element("generator")
xml = HTTParty.get("http://www.pauldix.net/atom.xml").body
Feedjira.parse(xml).generator
# => "TypePad"

If you want to add attributes for only one class you simply have to declare them in the class

# Add some GeoRss information
class Feedjira::Parser::RSSEntry
  element "georss:elevation", as: :elevation
end

# Fetch a feed containing GeoRss info and print them
url = "https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_week.atom"
xml = HTTParty.get(url).body
Feedjira.parse(xml).entries.each do |entry|
  puts "Elevation: #{entry.elevation}"
end

You can insert your own parser at the front of the available parser list by:

Feedjira.configure do |config|
  config.parsers.unshift(MyAwesomeParser)
end

Now when you call Feedjira.parse, MyAwesomeParser will be the first one to get a chance to parse the feed.

Feedjira can be configured to use a specific set of parsers and in a specific order:

Feedjira.configure do |config|
  config.parsers = [
    Feedjira::Parser::ITunesRSS,
    MyAwesomeParser,
    Feedjira::Parser::RSS
  ]
end

Feedjira can be configured to strip all whitespace but defaults to lstrip only:

Feedjira.configure do |config|
  config.strip_whitespace = true
end
