是否可以仅从HTML文件中提取所有文本？

Question

我要删除所有的格式，所有的文本就像你去任何网页的网站，用户Ctrl+A和Ctrl + C，然后使用Ctrl +V粘贴在记事本中的所有内容。你就会明白我提取所有text....only的意思了。让我们使用一个站点来更好地解释:这个站点：https://developer.palm.com/content/resources/develop/quick_start_ios.html

我想要的是：

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

这应该是可行的

<?php 

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

这就是大意。你可以做像str_replace('<br/>', '\n', $output)这样的事情来更好地格式化它。

Answer 2

我使用lynx，在你的终端上试试：

lynx -dump http://www.google.com

Answer 3

另一种方法是检索页面的body标记的值：

$html = new DOMDocument();

$html->loadHTMLFile("https://developer.palm.com/content/resources/develop/quick_start_ios.html");

$body = $html->getElementsByTagName("body");
$body = $body->item(0);

echo $body->nodeValue;
