Question

Now I’m fetching data from another url…
Here is my code:

require 'rubygems'
    require 'nokogiri'

    html = page.body

    doc = Nokogiri::HTML(html)
    doc.encoding = 'utf-8'

    rows = doc.search('//table[@id = "MainContent_GridView1"]//tr')
      @details = rows.collect do |row|
          detail = {}
          [
            [:car, 'td[1]/text()'],
            [:article, 'td[2]/text()'],
            [:group, 'td[3]/text()'],
            [:price, 'td[4]/text()'],
          ].each do |name, xpath|
            detail[name] = row.at_xpath(xpath).to_s.strip
          end
          detail
      end
    @details  

I tried to do it via array, not a hash. But I get a lot of errors…
Are there any ideas?
I need it for another method…

also i set data (this result hash) to another car here:

oem_art = []
    @constr_num.each do |o|
      as_oem = get_from_as_oem(o.ARL_SEARCH_NUMBER)
      if as_oem.present?
        oem_art << as_oem
      end
    end    

    @oem_art = oem_art.to_a.uniq

Do you just want to change a hash into an array? If so, just use the to_a method on your hash.

hash = {:a => "something", :b => "something else"}
array = hash.to_a
array.inspect #=> [[:a, "something"], [:b, "something else"]]
