XHTML validation

[Mark]

Syedur is on a PHP server, Abhi.

Try this:
[code:zcy2uwiiyz]
<?php // begin of page
function validXHTML($buffer){
$buffer = str_replace("&", "&amp;", $buffer);
$buffer = str_replace("\"", "&quote;", $buffer);
return $buffer;
}
ob_start("validXHTML");
?>
[/code:zcy2uwiiyz]
The output of the page goes through validXHTML(), where & and " are replaced. Then the buffer is returned and send to the client.

Disclaimer: I haven't tested this.. but I'm pretty confident it'll work

Parse Error on line 4... which is "return $buffer;"

Odd, it works fine on my system.

By the way, the forum software interpreted one part of the code wrong, I've updated my post now.

Actually, " (quotation mark) does't have to be written as &quot; (not &quote, if it's not in an attribute value of course.
You didn't include < though Mark, so the code should probably look something like this (kept the "):
[code:58etbbgoe4]
<?php // begin of page
function validXHTML($buffer){
$buffer = str_replace("&", "&amp;", $buffer);
$buffer = str_replace("\"", "&quot;", $buffer);
$buffer = str_replace("<", "&lt;", $buffer);
return $buffer;
}
ob_start("validXHTML");
?>

[/code:58etbbgoe4]

If I understand Syedur right, he's having problems with '&' and '<' which has to be encoded as e.g. & and < repectively. But this has to be done in HTML too.<hr id="quote"></blockquote id="quote"></span id="quote">

No.

Sorry but HTML is fine for your needs, gratuitous abuse of XHTML is nothing more than a waste of your time. Unless of course, you like wasting your time.

<blockquote id="quote"><span class="smalltext" id="quote">quote:<hr id="quote">
function validXHTML($buffer){
$buffer = str_replace("&", "&", $buffer);
$buffer = str_replace("\"", """, $buffer);
$buffer = str_replace("<", "<", $buffer);
return $buffer;
}
ob_start("validXHTML");
<hr id="quote"></blockquote id="quote"></span id="quote">

Do you really want to shag the performance and cachability of your page with code like that?

Well, they don't have to be escaped always, but '<' and '&' have special meaning in HTML (and you know for what). Try something like
[code:9buqeh3fnx]
x&y
a<b
[/code:9buqeh3fnx]
<blockquote id="quote"><span class="smalltext" id="quote">quote:<hr id="quote">Do you really want to shag the performance and cachability of your page with code like that?<hr id="quote"></blockquote id="quote"></span id="quote">
Blame it on Mark , I only modified his code.

Well I don't have an axe to grind man, but so many people abuse XHTML (like Flash heh).

[Syedur]

what is abuse of XHTML to you?
What do you think the purpose of it? How do you think people misuse it?

But, what if the content is dynamic and it is being generated via something else; server side and such. what do I do then?
<hr id="quote"></blockquote id="quote"></span id="quote">
Is it hard to generate directly escaped data?
<blockquote id="quote"><span class="smalltext" id="quote">quote:<hr id="quote">
No.

David is right, Tim.
You can do the same in xhtml and get only a *very* tiny warning:
[code:ky8eomwq3k]
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<title></title>
</head>
<body>
<div>
x & y
a < b
</div>
</body>
</html>
[/code:ky8eomwq3k]
as far as you dont write:
[code:ky8eomwq3k]
x&y
a<b
[/code:ky8eomwq3k]
funny stuff..
