如何使用mechanize/nokogiri获得简单但格式化的html

Question

require 'rubygems'
require 'mechanize'
  rational = Mechanize.new { |agent|
        agent.user_agent_alias = 'Windows Mozilla'
  }
  results = rational.get(ARGV[0])
  puts results.content 

给了我html，但我想要纯文本。最好的办法是可以格式化。

此代码将为您提供整个文档的无格式文本：

require 'mechanize'
require 'nokogiri'
rational = Mechanize.new { |agent|
    agent.user_agent_alias = 'Windows Mozilla'
}
document = Nokogiri::HTML(rational.get(ARGV[0]).content)
#This will give you very dirty result
#results = document.inner_text
#My suggestion is to extract text from some specific element
results = document.css("#content .my-element-with-some-contents").inner_text
