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
看法
<ul>
<%= debug @links.each.first %>
</ul>
调试输出

我需要的是循环访问链接数组,并使用标题和链接访问哈希,但我不知道如何这样做。
