require "nokogiri"

# 1) What is your favorite Ruby class/library or method and why?
# I will say pry, really handy gem to inspect code and dig while debugging.

# 2) Given HTML: "<div class="images"><img src="/pic.jpg"></div>" Using Nokogiri how would you select the src attribute from
# the image? Show me two different ways to do that correctly the the HTML given.
html = Nokogiri::HTML("<div class='images'><img src='/pic.jpg'></div>")
src_1 = html.xpath("//div/img/@src").first.value # => "/pic.jpg"
src_2 = html.css("div[class='images'] img").attr("src").value # =>"/pic.jpg"

# 3) If found HTML was a collection of li tags within a div with class="attr"
# how would you use Nokogiri to collect that information into one array?
html = Nokogiri::HTML("<div class='attr'><ul><li>batman</li><li>the joker</li></ul></div>")
info = html.xpath("//div[@class='attr']//ul//li").map(&:text) # => ["batman", "the joker"]

#4) Please collect all of the data presented into a key-value store. Please include code and the output.
# Given the following HTML:
html = Nokogiri::HTML(<<-HTML
