ruby on rails - Using the Mechanize gem with the Nokogirl gem? -

-

i'm trying scrape website requires authentication element on page id of #celltotal.

right now, using mechanize have logged page want access, using basic nokogiri functions like:

@selector = page.css("#celltotal").text

gives me error:

undefined method `css' #<mechanize::page:0x61234f8>

here have far:

agent = mechanize.new agent.get("example.com") agent.page.forms[0]["username_field"] = "username" agent.page.forms[0]["password_field"] = "password" agent.page.forms[0].submit  @selector = agent.page.css("#celltotal").text

how can select element on page?

you can use page.parser gain access underlying nokogiri object.

http://mechanize.rubyforge.org/mechanize/page.html#method-i-parser

require 'mechanize' agent = mechanize.new agent.get("http://stackoverflow.com/questions/23064821/using-the-mechanize-gem-with-the-nokogirl-gem/") agent.page.parser.class # => nokogiri::html::document agent.page.parser.css("#answer-23065003 .user-details a").text # => "akatakritos"
