是否可以阻止标准HTML注释显示在源代码中？

Question

I'm going to assume the answer is 'no' here, but since I haven't actually found that answer, I'm asking.

Quite basically, all I want to do is leave some HTML commenting in my files for 'author eyes only', simply to make editing the file later a much more pleasant experience.

<!-- Doing it like this --> leaves nice clean comments but they show up when viewing the page source after output.

I am using PHP, so technically I could <?PHP /* wrap comments in PHP tags */ ?> which would prevent them from being output at all, but if possible I'd like to avoid all of the extra arbitrary PHP tagging that would be needed for commenting throughout the file. After all, the point of commenting is to make the document feel less cluttered and more organized.

Is there anything else I could try or are these my best options?

Answer 1

No, anything in html will show up.

You could, have a script that parses the code, and removes the comments, before it puts it up on the server, and then you would have the original, and the uncommented source.

A tool to accomplish this: http://code.google.com/p/htmlcompressor/

Answer 2

I guess these are your best options, yes, unless you run the entire HTML output through some sort of cleanup module before being sent to the client.

Anything not wrapped in server side syntax will will be output to the client if not modified on its way out (through template engines, for example). This goes for most (probably all) server side languages).

Answer 3

你绝对可以编写一个使用正则表达式来删除HTML注释的解析器，但除非你已经在处理自己动手的CMS，否则很可能在这方面所涉及的工作超过了你不建议使用PHP注释的好处。
