Menu
I just started using Nokogiri this morning and I'm wondering how to perform a simple task: I just need to search a webpage for a div like this:
<div id="verify" style="display:none"> site_verification_string </div>
I want my code to look something like this:
require 'nokogiri'
require 'open-uri'
url = h(@user.first_url)
doc = Nokogiri::HTML(open(url))
if #SEARCH_FOR_DIV#.text == site_verification_string
@user.save
end
So the main question is, how do I search for that div using nokogiri?
Any help is appreciated.

For a simple way to get an element by its ID you can use .at_css("element#id")
Example for finding a div with the id "verify"
html = Nokogiri::HTML(open("http://example.com"))
puts html.at_css("div#verify")
This will get you the div and all the elements it contains

html = <<-HTML
<html>
<body>
<div id="verify" style="display: none;">foobar</div>
</body>
</html>
HTML
doc = Nokogiri::HTML html
puts 'verified!' if doc.at_css('[id="verify"]').text.eql? 'foobar'
