Remove JavaScript Comments

[The Little Guy]

I made a minifier (kinda), basically it removes newlines/tabs/2+ spaces in the html doc. What I would like to do is remove js comments in the html doc. BUT! I display php code on the page so I can not remove those comments.

 

so...

 

I would like to remove comments between the <script> and <style> tags, and ignore the ones between the <code> tags. Any suggestions on how to do this?

Why not copy/paste the code between those tags into the minifier, and then copy/paste it back afterwards?

That is kinda what I just started to do, then write a lexer on it. If there is a better/faster or any other suggestions way please let me know!

Is it me, or is this being greedy?

 

preg_match_all("/<script.+>.+<\/script>/isU", $template, $matches);
foreach($matches[0] as $match){
if(!empty($match)){
	echo "\n\n\n\n\n\n\n\n\n$match\n\n\n\n\n\n\n\n\n";
}
}

 

Output:

 

<script type="text/javascript" src="//jssnips.com/jquery/latest.js"></script><script type="text/javascript" src="//static1.phpsnips.com/js/anchorReader.js"></script>

 

I have about 5 - 10 places where script tags are located on a page, why is it pulling 2 script tags out as one match? They should each be their own match, and those two tags should have even matched.

Your .+ between the script tags in the regex requires that there be at least one character between the start and end tag for a match.  Since you have no characters between your start and end tags the match doesn't work on the individual pairs.  It matches both pairs as a whole because it counts the end/start tags as the required content in the middle.

 

Use .* for a zero or more match.
