Question

如何使用 Mechanize gem 从 html 页面上的“table”中获取“td”标签中的文本？

Answer 1

I almost always use mechanize with nokogiri. This guide helped me get started.

Something like this should work (Untested):

require 'mechanize'
require 'nokogiri'

agent = Mechanize.new
page = agent.get("http://www.google.com/")
doc = Nokogiri::HTML(page.body, "UTF-8")
doc.xpath('//td').each do |node|
  puts node.text
end
