You'll need this in your controller:

你需要在控制器中使用它：

require 'rss'
rss = RSS::Parser.parse(open('http://example.com/feed/posts').read, false)

From Parsing an RSS feed with Ruby.

从使用Ruby解析RSS提要。

I'd recommend to use gem called Feedzirra

我建议使用名为Feedzirra的宝石

require 'feedzirra'

# fetching a single feed
feed = Feedzirra::Feed.fetch_and_parse("http://www.knews.kg/ru/politics/rss/")

# feed and entries accessors
feed.title                  # => "Политика » K-News: Новости страны"
feed.description            # => "Политика страны"

while installing (Ubuntu 12.04) i had problem with compiling, try this

虽然安装（Ubuntu 12.04）我有编译问题，试试这个

sudo apt-get install libcurl4-gnutls-dev

sudo apt-get install libcurl4-gnutls-dev
