Question

我试图在Ruby 2.1.0中使用Nokogiri解析表。这是我的桌子。如你所见，桌子里面有桌子。这是父表的一个元素。我想一起解析每2个标签。我该怎么办？

总之，我想先将2个tr组合在一起，然后将表格放在2. tr。

中。

RUBY CODE：

require 'nokogiri'
require 'sanitize'

doc=Nokogiri(File.open('bannerweb.html'))

items = doc.xpath('(//table)[3]/tr')

items.collect do |row|
if row.at_xpath('th/a/text()') != nil
    course = row.at_xpath('th/a/text()').text 
    course.split(' - ').each do |item|
        p item
    end
end
if row.at_xpath('td') != nil
    info = row.at_xpath('td')
    table = info.at_xpath('tr')
    p table.inspect
end
end
