Удаление предупреждения DocDocument при разборе содержимого страницы
Я пытаюсь разобрать содержание любого URL. Который не должен содержать какой-либо HTML-код. Это работает нормально, но выдает кучу ошибок при чтении содержимого по указанному URL. Как убрать это предупреждение?
<?php
$url= 'http://stackoverflow.com/questions/12097352/how-can-i-parse-dynamic-content-from-a-web-page';
$doc = new DOMDocument();
$doc->loadHTMLFile($url);
$xpath = new DOMXPath($doc);
foreach($xpath->query("//script") as $script) {
$script->parentNode->removeChild($script);
}
$textContent = $doc->textContent; //inherited from DOMNode
echo $textContent;
?>
Предупреждения:
