I have a php file in application\views\article.php
article.php content:
<!DOCTYPE html>
<html prefix='og: http://ogp.me/ns#'>
<head>
<title>test</title>
</head>
<body>
<div> test div1 </div>
<div> test div2 </div>
</body>
</html>
When I use $this->load->view() to load article.php template and use DomDocument to get dom.
$html=$this->load->view('article','',TRUE);
$doc = new DomDocument;
$doc->loadHTML($html);
echo $doc->saveXML($doc->getElementsByTagName('div')->item(0));
// or echo $doc->saveXML();
have the error message: Message: DOMDocument::loadHTML(): Unexpected end tag : meta in Entity, line: 4
but whe I use this:
$html='<!DOCTYPE html>
<html prefix=\'og: http://ogp.me/ns#\'>
<head>
<title>test</title>
</head>
<body>
<div> test div1 </div>
<div> test div2 </div>
<p>Directory </p>
</body>
</html>';
$doc->loadHTML($html);
echo $doc->saveXML($doc->getElementsByTagName('div')->item(0));
// or echo $doc->saveXML();
this is success.
gettype($html) to two methods of $html, both are strings.
Try hide the warning with
libxml_use_internal_errors(true);
Or:
@$doc->loadHTML($html);
The warning is because the HTML returned by $this->load->view('article','',TRUE); is invalid, loadHTML() resolve this but show the warnings.
