Удалите все теги HTML + содержимое из текста

Хорошо, так, как это может показаться, я все еще не в состоянии сделать правильно. Я попытался с RegEx, я даже попытался разбор DOM, но все еще не смог понять это правильно.

Основываясь на ответе в моем предыдущем вопросе ( Попытка удалить HTML-теги (+ контент) из String ), вот что я получил:

• Компилировать регулярное выражение в PHP
• Регулярное выражение PHP для надежной проверки пароля
• Найти всю строку, содержащую слово с регулярными выражениями php
• Получить цену товара на рынке сообщества Steam с помощью PHP и Regex
• Поиск подстановочных файлов vqmod с использованием regex

public static function removeHtmlTags($str) { $dom = new DOMDOcument(); $errorState = libxml_use_internal_errors(true); $dom->loadHTML($str); $xpath = new DOMXPath($dom); $node = $xpath->query('//body/p/text()')->item(0); if (isset($node->textContent)) $ret = $node->textContent; else $ret=""; libxml_use_internal_errors($errorState); return $ret; } 

Это, похоже, делает трюк большую часть времени, однако вот уловка …

Это (ну, если вы не можете понять, что это такое, это Википедия Infobox ):

И мне интересно:

Что случилось с |native_name = {{lang|it|''Repubblica italiana<!--italiana is without uppercase; see Italian wiki-->''}} |native_name = {{lang|it|''Repubblica italiana<!--italiana is without uppercase; see Italian wiki-->''}}

Не может быть:

|native_name = {{lang|it|''Repubblica italiana''}}

Вместо этого, похоже, он избавляется от комментария HTML и последующего текста.

Есть идеи?
