## Finding Quiz Responses (#200)
Hola Rubyists,
The new Rubyquiz website is perfect... almost. It has the quizzes, it
has the summaries, but one thing that it is missing are the links to
the mailing list responses.
This week's quiz is to write a program to gather the responses for
each quiz on the ruby-talk mailing list. The data needed for the
responses
are:
- The quiz the response is for
- The name of the person who submitted the response
- A URL to link to the response
Have Fun!

Finding all the responses to this week's quiz was easy: no responses!
In other news, Luke Cowell made significant contributions to the Ruby
Quiz site by adding an RSS feed
(

/q...) and adding a prominent link to
the current quiz. Thank you Luke, for making Ruby Quiz even better!

It's late, but it's here.. my very first ruby quiz submission:
#!/usr/bin/env ruby
require 'rubygems'
require 'hpricot'
require 'open-uri'
require 'cgi'
def build_quiz_uri(quiz_num)
query = CGI::escape("subject:(+#{quiz_num}) +quiz")
base_url = "
http://www.ruby-...
search?qu...
uri_string = (base_url + query)
URI.parse(uri_string)
end
def get_quiz_response_url(uri_string)
doc = Hpricot(open(uri_string))
quiz_table = doc.at("table[@class='topics list]")
quizzes = quiz_table.search("tr[@class$='new-posts ']")
highest_replies = 0
link = ""
#find the quiz that has the right subject and has the most replies
quizzes.each do |quiz|
subject = quiz.at("td[@class='subject']/a").innerHTML
quiz_subject = "#" + Quiz_num.to_s
if(subject.include?(quiz_subject))
replies = quiz.at("td[@class='replies']").innerHTML.to_i
if(replies > highest_replies)
highest_replies = replies
link = quiz.at("td[@class='subject']/a")[:href]
end
end
end
#trim the excess anchor
link.gsub(/#.*$/, "")
end
def get_responses(url)
doc = Hpricot(open(url))
response_elements = doc.search(".post")
responses = []
response_elements.inject([]) do |responses, response|
link = url + response.search("div[@class='subject]").at("a")[:href]
author =
response.search("span[@class]='name'").text.split("(").first.strip
responses << {:link => link, :author => author}
end
#remove the first quiz (which is from the quizmaster)
responses.delete_at(0)
#if the summary has been posted, we want to remove that too
#it's difficult to know if we should actually remove the response...
if(responses.length > 0)
if(QuizMaster_Name.include?(responses.last[:author]))
responses.pop
end
end
responses
end
Quiz_num = 100
QuizMaster_Name = ["Di Mo", "James Gray"]
query_uri = build_quiz_uri(Quiz_num)
response_path = get_quiz_response_url(query_uri)
response_url = query_uri.scheme + "://" + query_uri.host + response_path
puts get_responses(response_url).to_yaml
