引入nokogiri XML解析使用Rails

我看了好多TUTS，但this一个似乎已经得到了我在哪里，我引入nokogiri XML解析使用Rails

控制器

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

视图

<ul> 
    <%= debug @links.each.first %> 
</ul>

调试出来把

{"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">]>]}

我需要的是循环链接数组并访问哈希标题和链接，但我不知道该怎么做。

如果我的理解正确，你只需要从xpath节点获取内部文本。

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