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 

给我HTML但我想纯文本。最好的是，如果它可以格式化。

Answer 1

此代码会给你整个文档的纯无格式的文本：

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
