Nokogiri XML Parsing with Rails

Question

I looked at a lot of tuts but this one seems to have got me where I am

controller

  def index
      require 'nokogiri'
      doc = Nokogiri::XML(open("http://sports.yahoo.com/top/rss.xml"))

      @links = doc.xpath('//item').map do |i|
      {'title' => i.xpath('title'), 'link' => i.xpath('link'), 'description' => i.xpath('description')}
      end
  end

view

debug out put

{"title"=>[#<Nokogiri::XML::Element:0x8199ce34 name="title" children=[#<Nokogiri::XML::Text:0x8199c6f0 "Kolb to get start for Eagles vs. Falcons (AP)">]>], "description"=>[#<Nokogiri::XML::Element:0x8199b660 name="description" children=[#<Nokogiri::XML::Text:0x8199a594 "Kevin Kolb will make his second straight start in place of the injured Michael Vick when the Philadelphia Eagles host Atlanta on Sunday. Eagles coach Andy Reid says Vick practiced Friday for the first time since sustaining a rib cartilage injury on Oct. 3. There's a chance Vick will be the backup quarterback against his former team.">]>], "link"=>[#<Nokogiri::XML::Element:0x81999f40 name="link" children=[#<Nokogiri::XML::Text:0x81999b58 "http://us.rd.yahoo.com/sports/rss/top/SIG=11npql9k5/*http%3A//sports.yahoo.com/nfl/news?slug=ap-eagles-qbs"&gt;]&gt;]}

What I need is to loop over the links array and access the hash with the title and link, but I don't know how to do that.

If I'm understanding correctly, you just need to get the inner text from the xpath nodes.

{'title' => i.xpath('title').inner_text, 'link' => i.xpath('link').inner_text, 'description' => i.xpath('description').inner_text }
