How to parse invalid HTML?

Question

PHP

Please tell me how to parse invalid HTML?
Previously, I always used Simple HTML DOM, the result \ speed was fine, but it does not work with invalid HTML - it goes into recursion.

Answer 1

Регулярками очевидно же

Answer 2

Однозначно сначала Tidy. Отлично исправляет весь невалид

Answer 3

Tidy. And there is no need to look for alternatives.
Here is one of my use cases for example.

$options = 	array("indent" => false, 
        "output-xml" => true, 
        "clean" => true,
        "drop-proprietary-attributes" => true,
        "drop-font-tags" => true,
        "drop-empty-paras" => true,
        "hide-comments" => true,
        "join-classes" => true,
        "join-styles" => true,
        "show-body-only" => false); 
              
$tidy = new tidy();
$str = $tidy->parseString($page, $options, 'utf8'); // $page содержит невалидный html
$tidy->cleanRepair();
echo $tidy; // валидный html

With a list of options, I advise you to play around on your own.
