Menu
I'm using php extension tidy-html to clean up php output. I know that tidy removes invalid tags and can't even handle HTML5 doctype, but I'm using tag <menu> which used to be in HTML specifications. However, it gets changed for <ul> anyway.
Oddly enough, It didn't do so before. I changed the tidy config and it has break. Now I've turned off all options that messes with tags, but it didn't help.
My script is quite verbose:
$tidy_config = array(
'char-encoding' => 'utf8',
'output-encoding' => 'utf8',
'output-html' => true,
'numeric-entities' => false,
'ascii-chars' => false,
'doctype' => 'loose',
'clean' => false,
'bare' => false,
'fix-uri' => true,
'indent' => true,
'indent-spaces' => 2,
'tab-size' => 2,
'wrap-attributes' => true,
'wrap' => 0,
'indent-attributes' => true,
'join-classes' => false,
'join-styles' => false,
'fix-bad-comments' => true,
'fix-backslash' => true,
'replace-color' => false,
'wrap-asp' => false,
'wrap-jste' => false,
'wrap-php' => false,
'wrap-sections' => false,
'drop-proprietary-attributes' => false,
'hide-comments' => false,
'hide-endtags' => false,
'drop-empty-paras' => true,
'quote-ampersand' => true,
'quote-marks' => true,
'quote-nbsp' => true,
'vertical-space' => true,
'wrap-script-literals' => false,
'tidy-mark' => true,
'merge-divs' => false,
'repeated-attributes' => 'keep-last',
'break-before-br' => false
);
$tidy_config2 = array(
'tidy-mark' => false,
'vertical-space' => false,
'hide-comments' => true,
'indent-spaces' => 0,
'tab-size' => 1,
'wrap-attributes' => false,
'numeric-entities' => true,
'ascii-chars' => true,
'hide-endtags' => true,
'indent' => false
);
$tidy_config = array_merge($tidy_config, $tidy_config2);
$dtm = preg_match(self::doctypeMatch, $output, $dt);
$output = tidy_repair_string($output, $tidy_config, 'utf8');
// tidy screws up doctype --fixed
if($dtm)
$output = preg_replace(self::doctypeMatch, $dt[0], $output);
$output = preg_replace('!>[\n\r]+<!', '><', $output);
unset($tidy_config);
return $output;
Note that it is more complicated than this (hence the two arrays). I've just cut off unnecessary code.

I don't think my answer is very... neat. It's more of a hakish way to use HTMLTidy with HTML5 (which currently it does not support). To accomplish that I use regex to parse HTML, which, according to most, is the the root of all evil or the cthulhu way. If someone knows a better way, please enlighten us, since I don't feel very secure in using regex to parse html. I've tested it with many examples but I'm quite sure it's not bullet proof.
The menu tag was deprecated in HTML4 and XHTML1, being replaced by ul (unordered list). It was, however, redefined in HTML5 and hence is a valid tag according to HTML5 specifications. SinceHTMLTidy does not support HTML5 and uses XHTML or HTML specifications, as the OP pointed, it replaces the then deprecated tag menu to ul (or adds the ul tag), even when you specifically tell it not to.
This function replaces the menu tag with a custom tag prior to parsing it with tidy. It then replaces the custom tag with menu again.
function tidyHTML5($buffer)
{
$buffer = str_replace('<menu', '<mytag', $buffer);
$buffer = str_replace('menu>', 'mytag>', $buffer);
$tidy = new tidy();
$options = array(
'hide-comments' => true,
'tidy-mark' => false,
'indent' => true,
'indent-spaces' => 4,
'new-blocklevel-tags' => 'menu,mytag,article,header,footer,section,nav',
'new-inline-tags' => 'video,audio,canvas,ruby,rt,rp',
'doctype' => '<!DOCTYPE HTML>',
//'sort-attributes' => 'alpha',
'vertical-space' => false,
'output-xhtml' => true,
'wrap' => 180,
'wrap-attributes' => false,
'break-before-br' => false,
'char-encoding' => 'utf8',
'input-encoding' => 'utf8',
'output-encoding' => 'utf8'
);
$tidy->parseString($buffer, $options, 'utf8');
$tidy->cleanRepair();
$html = '<!DOCTYPE HTML>' . PHP_EOL . $tidy->html();
$html = str_replace('<html lang="en" xmlns="http://www.w3.org/1999/xhtml">', '<html>', $html);
$html = str_replace('<html xmlns="http://www.w3.org/1999/xhtml">', '<html>', $html);
//Hackish stuff starts here
//We use regex to parse html, which is usually a bad idea
//But currently there is no alternative to it, since tidy is not MENU TAG friendly
preg_match_all('/\<mytag(?:[^\>]*)\>\s*\<ul>/', $html, $matches);
foreach($matches as $m) {
$mo = $m;
$m = str_replace('mytag', 'menu', $m);
$m = str_replace('<ul>', '', $m);
$html = str_replace($mo, $m, $html);
}
$html = str_replace('<mytag', '<menu', $html);
$html = str_replace('</ul></mytag>', '</menu>', $html);
$html = str_replace('mytag>', 'menu>', $html);
return $html;
}
TEST:
header("Content-type: text/plain");
echo tidyHTML5('<menu><li>Lorem ipsum</li></menu><div></div><menu ><a href="#">lala</a><form id="jj"><button>btn</button></form></menu><menu style="color: white" id="nhecos"><li>blabla</li><li>sdfsdfsdf</li></menu>');
OUTPUT:
<!DOCTYPE HTML>
<html>
<head>
<title></title>
</head>
<body>
<menu>
<li>Lorem ipsum
</li>
</menu><menu style="color: white" id="nhecos">
<li>blabla
</li>
<li>sdfsdfsdf
</li>
</menu>
</body>
</html>
