php - 是否可以仅从 HTML 文件中提取所有文本？

Question

我正在考虑删除所有格式，所有文本就像您转到网站的任何页面，用户 Ctrl+A 和 Ctrl + C，然后使用 Ctrl + V 将所有内容粘贴到记事本中。你会通过提取所有文本来理解我的意思……只是。让我们使用一个网站来更好地解释:这个网站: https://developer.palm.com/content/resources/develop/quick_start_ios.html

If you've been developing for iOS® and are looking to expand your audience, we're here to help. Getting started with webOS is easy! If your current focus is OpenGL/SDL, then the transition will be simplicity itself. We have lots of great stories of developers porting their OpenGL apps very quickly. You can use the publicly available 3.0 SDK to do OpenGL/SDL development now with the included Plug-in Development Kit (PDK). Best of all, the PDK integrates nicely with  Xcode.

If your focus is web app development, you'll want to look at Enyo, our next-generation JavaScript framework, which is included in the 3.0 SDK.

Ready to get started?

Download the SDK
It's free! (While you're at it, sign up for the Developer Program.)

Try the Enyo tutorial or the OpenGL sample app
Choose the sample that's most appropriate for your skill set.

Answer 1

这应该可行

<?php 

echo strip_tags(file_get_contents("https://developer.palm.com/content/resources/develop/quick_start_ios.html"));

这就是总体思路。你可以做类似 str_replace('<br/>', '\n', $output) 的事情更好地格式化它。
