A PCRE in PHP

Easy one for those who know regex's well! If I have a big long string that basically contains a messy HTML page, I want to strip out: 1: All HTML comments 2: All javascript comments 3: All whitespace than can be removed .. without breaking anything. It sounds easy enough, but there's some odd quirks that make it more challenging than I want to handle :) See the full spec for the way I see it... Cheers, C ## Deliverables Easy one for those who know regex's well! If I have a big long string that basically contains a messy HTML page, I want to strip out: 1: All HTML comments 2: All javascript comments 3: All whitespace than can be removed Here's the HTML comments regex: preg_replace('/;/', '', $buffer); Problem 1: If you follow that and you know HTML, you'll know that it's great unless you're inside a tag pair that uses comments to protect its content from older browser that don't understand (most common I guess being {script} and {style} tags. Problem 2: Javascript comments that might appear after a line of code, not on their own - eg: var problemVar; // this variable is commented Problem 3: Whitespace that appears inside {pre} tags needs to remain untouched (I don't know if there's any others like that). Those are the problems that I can think of, there might be more - notice the brief says "without breaking anything"! :) Nice regex problems if anyone fancies them anyway :) 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Complete ownership and distribution copyrights to all work purchased. ## Platform PHP / Linux / use PCRE's, not PHP's own regex stuff
