干净的html空白和换行

Question

我如何清理双空格和换行符的html输出，但不使用php修改textarea和pre标签中的内容？

Answer 1

First of all, I would rather say : don't do this :

• There is a risk that you'll introduce errors
• This is not needed : your cleaned HTML will be rendered the same as the original one
• You will not gain much on the page's size -- there are many other optimizations that should be done before trying to minify HTML.

Still, if you really want to do that, you are probably looking for an HTML Minifier .

There are several tools that exist, to do that ; here are a couple of exemples :

• In PHP : https://code.google.com/p/minify/source/browse/trunk/min/lib/Minify/HTML.php
• In PHP : you might want to take a look at the source-code of smarty's {strip} tag
• In JAVA : https://code.google.com/p/htmlcompressor/
• In JavaScript : https://github.com/kangax/html-minifier
