数据抓取多个数组创建和排序

我们正在努力削减课程名称，资格和课程持续时间，并将每个课程存储在一个单独的arrays中。 下面我们拉出所有这些，但它似乎是随机顺序，有些部分可能按页面排序等。想知道是否有人能够提供帮助。

require 'mechanize' mechanize = Mechanize.new @duration_array = [] @qual_array = [] @courses_array = [] page = mechanize.get('http://search.ucas.com/search/results?Vac=2&AvailableIn=2016&IsFeatherProcessed=True&page=1&providerids=41') page.search('div.courseinfoduration').each do |x| puts x.text.strip page.search('div.courseinfooutcome').each do |y| puts y.text.strip end while next_page_link = page.at('.pager a[text()=">"]') page = mechanize.get(next_page_link['href']) page.search('div.courseinfoduration').each do |x| name = x @duration_array.push(name) puts x.text.strip end end while next_page_link = page.at('.pager a[text()=">"]') page = mechanize.get(next_page_link['href']) page.search('div.courseinfooutcome').each do |y| name = y @qual_array.push(name) puts y.text.strip end end page.search('div.coursenamearea h4').each do |h4| puts h4.text.strip end while next_page_link = page.at('.pager a[text()=">"]') page = mechanize.get(next_page_link['href']) page.search('div.coursenamearea h4').each do |h4| name = h4.text @courses_array.push(name) puts h4.text.strip end end end
