# = RSS reading and writing
|
|
#
|
|
# Really Simple Syndication (RSS) is a family of formats that describe 'feeds,'
|
|
# specially constructed XML documents that allow an interested person to
|
|
# subscribe and receive updates from a particular web service. This portion of
|
|
# the standard library provides tooling to read and create these feeds.
|
|
#
|
|
# The standard library supports RSS 0.91, 1.0, 2.0, and Atom, a related format.
|
|
# Here are some links to the standards documents for these formats:
|
|
#
|
|
# * RSS
|
|
# * 0.9.1[http://www.rssboard.org/rss-0-9-1-netscape]
|
|
# * 1.0[http://web.resource.org/rss/1.0/]
|
|
# * 2.0[http://www.rssboard.org/rss-specification]
|
|
# * Atom[http://tools.ietf.org/html/rfc4287]

|
# == Consuming RSS
|
|
#
|
|
# If you'd like to read someone's RSS feed with your Ruby code, you've come to
|
|
# the right place. It's really easy to do this, but we'll need the help of
|
|
# open-uri:
|
|
#
|
|
# require 'rss'
|
|
# require 'open-uri'
|
|
#
|
|
# url = 'http://www.ruby-lang.org/en/feeds/news.rss'
|
|
# open(url) do |rss|
|
|
# feed = RSS::Parser.parse(rss)
|
|
# puts "Title: #{feed.channel.title}"
|
|
# feed.items.each do |item|
|
|
# puts "Item: #{item.title}"
|
|
# end
|
|
# end
|
|
#
|
|
# As you can see, the workhorse is RSS::Parser#parse, which takes the source of
|
|
# the feed and a parameter that performs validation on the feed. We get back an
|
|
# object that has all of the data from our feed, accessible through methods.
|
|
# This example shows getting the title out of the channel element, and looping
|
|
# through the list of items.
|
|
#
|
|
# == Producing RSS
|
|
#
|
|
# Producing our own RSS feeds is easy as well. Let's make a very basic feed:
|
|
#
|
|
# require "rss"
|
|
#
|
|
# rss = RSS::Maker.make("atom") do |maker|
|
|
# maker.channel.author = "matz"
|
|
# maker.channel.updated = Time.now.to_s
|
|
# maker.channel.about = "http://www.ruby-lang.org/en/feeds/news.rss"
|
|
# maker.channel.title = "Example Feed"
|
|
#
|
|
# maker.items.new_item do |item|
|
|
# item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"
|
|
# item.title = "Ruby 1.9.2-p136 is released"
|
|
# item.updated = Time.now.to_s
|
|
# end
|
|
# end
|
|
#
|
|
# puts rss
|
|
#
|
|
# As you can see, this is a very Builder-like DSL. This code will spit out an
|
|
# Atom feed with one item. If we needed a second item, we'd make another block
|
|
# with maker.items.new_item and build a second one.
