Subject: Trouble with Pushing Arrays to Arrays

Hello everyone! I'm having some trouble with pushing an array to another
array. Maybe this is an easy fix that I'm just not seeing? Here's my
code:

require 'nokogiri'
require 'open-uri'

url = 'C:\\users\\derek\\desktop\\Schedule2.html'
doc = Nokogiri::HTML(open(url))

raw_course_list = Array.new
temp = Array.new

doc.css("tr").each { |row| # Search through every row
     row.css("td").each { |column|
          temp.push(column.text.strip)
     }
     # puts temp.class #=> Array
     # puts temp.size #=>  20
     # puts temp[7] # E.g. => "Intro to Financial Accounting"
     raw_course_list.push(temp)
     # puts "raw_course_list[0]: " + raw_course_list[0].to_s #  ****
Always returns the last temp pushed, not what should be at [0] (the
first array ever pushed) ****
     # print "raw_course_list.size: ", raw_course_list.size, "\n" #
Correctly increases +1 each push
     temp.clear
}

puts raw_course_list.each { |i| puts i.to_s} # **** Prints out line
after line of empty arrays ****
