在Rails中将HTML添加到我的RSS/Atom提要

默认的rails XML构建器会转义所有HTML,例如:

atom_feed do |feed|  
  @stories.each do |story|  
    feed.entry story do |entry|   
      entry.title story.title
      entry.content "foo"
    end  
  end  
end

foo

entry.content "foo", :type => "html"

entry.content "type" => "html" do
    entry.cdata!(post.content)
end
