Nokogiri Woes


#1

Hi Chefs,
I am trying to get Chef to work with Nokogiri but not having any success. The docs I am finding aren’t helping me. Would someone be able to point me to the correct docs? I am sure I am missing it. Thanks!

Can you be more specific about what you are trying to do? Do you just mean using the nokogiri gem in a Chef recipe?

Yes, I have a ruby block that changes some nodes in an xml file and it works fine via the command line but not in my chef recipe.

IE:

ruby_block “edit config” do
block do
f = File.open(“config.xml”)
fw = File.open(“config.xml.1”, ‘w’)

    config = Nokogiri::XML(f)

    config.css("server").each do |node|
     puts "\r\n[debug] Before: server= \r\n#{node}"
     node.children.remove
     node.content = "jennie.ldap.server.com"
     puts "\r\n[debug] After: server=\r\n#{node}"
     fw.print config.to_s
    end

end

I get the following errors:

NameError: uninitialized constant Chef::Recipe::Nokogiri

If I add requires nokogiri:

undefined method `nokogiri’ for Chef::Resource::RubyBlock

Being a newbie in chef/ruby, I am sure I am issuing something but not sure where to look Thanks! :smiley:

Add this to the top of the recipe:

chef_gem 'nokogiri’
require ‘nokogiri’
