leveli:	textI"RSS reading and writing;To:RDoc::Markup::BlankLineo:RDoc::Markup::Paragraph;[	I"SReally Simple Syndication (RSS) is a family of formats that describe 'feeds,' ;TI"Lspecially constructed XML documents that allow an interested person to ;TI"Rsubscribe and receive updates from a particular web service. This portion of ;TI"Jthe standard library provides tooling to read and create these feeds.;T@o;
;[I"SThe standard library supports RSS 0.91, 1.0, 2.0, and Atom, a related format. ;TI"FHere are some links to the standards documents for these formats:;T@o:RDoc::Markup::List:

i;I"Consuming RSS;T@o;
;[I"RIf you'd like to read someone's RSS feed with your Ruby code, you've come to ;TI"Nthe right place. It's really easy to do this, but we'll need the help of ;TI"open-uri:;T@o:RDoc::Markup::Verbatim;[I"require 'rss'
;TI"require 'open-uri'
;TI"
;TI"8url = 'http://www.ruby-lang.org/en/feeds/news.rss'
;TI"open(url) do |rss|
;TI"%  feed = RSS::Parser.parse(rss)
;TI"+  puts "Title: #{feed.channel.title}"
;TI"!  feed.items.each do |item|
;TI"$    puts "Item: #{item.title}"
;TI"  end
;TI"	end
;T:@format0o;
;[
I"SAs you can see, the workhorse is RSS::Parser#parse, which takes the source of ;TI"Sthe feed and a parameter that performs validation on the feed. We get back an ;TI"Pobject that has all of the data from our feed, accessible through methods. ;TI"RThis example shows getting the title out of the channel element, and looping ;TI"through the list of items.;T@S;	;
i;I"Producing RSS;T@o;
;[I"OProducing our own RSS feeds is easy as well. Let's make a very basic feed:;T@o;;[I"require "rss"
;TI"
;TI".rss = RSS::Maker.make("atom") do |maker|
;TI"%  maker.channel.author = "matz"
;TI"-  maker.channel.updated = Time.now.to_s
;TI"J  maker.channel.about = "http://www.ruby-lang.org/en/feeds/news.rss"
;TI",  maker.channel.title = "Example Feed"
;TI"
;TI"&  maker.items.new_item do |item|
;TI"`    item.link = "http://www.ruby-lang.org/en/news/2010/12/25/ruby-1-9-2-p136-is-released/"
;TI"4    item.title = "Ruby 1.9.2-p136 is released"
;TI"&    item.updated = Time.now.to_s
;TI"  end
;TI"	end
;TI"
;TI"puts rss
;T;0o;
;[I"QAs you can see, this is a very Builder-like DSL. This code will spit out an ;TI"RAtom feed with one item. If we needed a second item, we'd make another block ;TI"6with maker.items.new_item and build a second one.;T@S;	;
