Nokogiri: to_s WITHOUT html surrounding's tags?
Hi all
n = Nokogiri::HTML("<h1>H1</h1>")
n.to_s
# => <!DOCTYPE html PUBLIC \"-//W3C//DTD HTML 4.0 Transitional//EN\"

Loading xml document using Nokogiri and retrieving CDATA element
This is an extension of my last post (problems with REXML) which has me
looking to Nokogiri again. The reason I am not using Nokogiri is I can not
seem to find a way to get CDATA out of a Nokogiri document.
First, can you tell me if I am loading my document correctly, because when I
call my_document.to_xml, I only get one line back:
(rdb:1) test_file = Nokogiri::XML(mismo_xml_file)

Minitest mock or stub methods
Hi
I''m building a small library to use in my Rails app which interacts with a
3rd party API. It fetches artists and tracks.
So I have:
lib/my_lib.rb
lib/my_lib/artist.rb
lib/my_lib/track.rb
To get an artist I do
artist = MyLib::Artist.find("Oasis")
Which returns an instance of Artist if it finds (via 3rd party API) it or
nil otherwise.
Then I can call artist.tracks which
