Parse Contents not in html tags Nokogiri

Question 1

The html is really not that bad, and you were on the right track with br + strong, that's the thing you want to iterate:

doc.search('.min-width div form').each do |form|
  title = form.at('span').text
  description = form.at('br').next.text

  form.search('br + strong').each do |el|
    cinema = el.text
    phones = []
    while next_el = el.at('+ a', '+ br + a')
      el = next_el
      phones << el.text
    end
    times = el.at('+ br').next.text        
  end
end

Question 2

This is horrible HTML :/ it's invalid with 451 errors and 9 warnings. Nothing semantic, so you have to depend on the structure, which is likely to change, breaking your scraping.

Nonetheless, you can get each of these by using sibling methods:

doc.css('.min-width div form').each do |node|
  description = node.at_css('br').next_sibling.text
  puts description.strip
  puts '-'*10
end
