nested loop for xpath

From: Soichi Ishida <lists@...>
Date: 2013-04-05 05:57:15 UTC
List: ruby-talk #406510
Rails 1.9.3

I am scraping a web page,
http://en.wikipedia.org/wiki/List_of_birds_by_common_name

using Nokogiri and Xpath

I want all the names of the birds listed there.

xpath1 = '//div[@id='bodyContent']/div[@id='mw-content-text']/ul[1]'

should get a group of birds

Great Tinamou
Andean Tinamou
Elegant Crested Tinamou
Little Tinamou
Slaty-breasted Tinamou
Thicket Tinamou

I need to get each one of these names and tried nested loop

xpath1 = '//div[@id='bodyContent']/div[@id='mw-content-text']/ul'
doc = Nokogiri::HTML(open(url))
categories = doc.xpath(xpath1)

categories.each do | c |
    c.xpath('/li').each do | n |
         p n.text
    end
end


gives empty values.
Can anyone tell why?  or are there better ways?

soichi
