我正在尝试解析任何 url 的内容。不应该满足任何 html 代码。这工作正常,但在阅读给出的 url 上的内容时会出现一堆错误。如何删除此警告?
<?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;
?>
警告:
