Ruby Nokogiri提取HTML选项卡值

Question

there's a webpage with many pages. And I'd like to know the total pages for each search. Like the pictures shown below. Since the last page is page 41 and it becomes un_clickable. So I want to extract that value 41 from those 2 span tags.

Any help? I tried with xpath. But would prefer a CSS solution

Thanks

page_temp = Nokogiri::HTML(browser.html)  
page_temp.xpath('tr[@td = "colspan="32""]').each do |node|
    puts node.text

Since you are using Ruby here's a simple code you can use

page_temp = Nokogiri::HTML(browser.html)  
all_pages = page_temp.search("td[colspan='32'] tr td")
puts all_pages.map{|p| p.text}  # list all page numbers
puts all_pages.last.text        # list the last page number
