How to get the content of an XML node using XPath and Nokogiri

I have code like this:

@doc = Nokogiri::HTML(open(url)
@doc.xpath(query).each do |html|

  puts html # how get content of a node
end

How do I get the content of the node instead of something like this:

<li class="stat">
Solution

  • This is the Synopsis example in the README file for Nokogiri showing one way to do it using CSS, XPath or a hybrid:

    require 'nokogiri'
require 'open-uri'

# Get a Nokogiri::HTML:Document for the page we’re interested in...

doc = Nokogiri::HTML(open('http://www.google.com/search?q=tenderlove'))

# Do funky things with it using Nokogiri::XML::Node methods...

####
# Search for nodes by css
doc.css('h3.r a.l').each do |link|
  puts link.content
end

####
# Search for nodes by xpath
doc.xpath('//h3/a[@class="l"]').each do |link|
  puts link.content
end

####
# Or mix and match.
doc.search('h3.r a.l', '//h3/a[@class="l"]').each do |link|
  puts link.content
end
