我到处搜索，我发现的只是用 Nokogiri 做 CSS 选择，我所追求的只是摆脱所有 HTML 标签。
例如这个:
<html>
<head><title>My webpage</title></head>
<body>
<h1>Hello Webpage!</h1>
<div id="references">
<p><a href="http://www.google.com">Click here</a> to go to the search engine Google</p>
<p>Or you can <a href="http://www.bing.com">click here to go</a> to Microsoft Bing.</p>
<p>Don't want to learn Ruby? Then give <a href="http://learnpythonthehardway.org/">Zed Shaw's Learn Python the Hard Way</a> a try</p>
</div>
<div id="funstuff">
<p>Here are some entertaining links:</p>

<li><a data-category="news" href="http://reddit.com">Reddit</a></li>
<li><a href="http://kathack.com/">Kathack</a></li>
<li><a data-category="news" href="http://www.nytimes.com">New York Times</a></li>
</ul>
</div>
<p>Thank you for reading my webpage!</p>
</body>
<p>Addition</p>
</html>

应该输出为:
Hello Webpage!
Click here to go to the search engine Google
Or you can click here to go to Microsoft Bing.

我如何使用 Nokogiri 做到这一点？另外，我还能做些什么来抓取其他代码，例如 Javascript？
最佳答案
require 'nokogiri'
html = %q{
<html>
<head><title>My webpage</title></head>
<body>
<h1>Hello Webpage!</h1>
<div id="references">
<p><a href="http://www.google.com">Click here</a> to go to the search engine Google</p>

}
doc = Nokogiri::XML(html)
body = doc.search('body')
puts body.text.gsub(/<.*?\/?>/, '')
