Examples

Example #1 Dom\HTMLDocument::createFromString() example

$dom = Dom\HTMLDocument::createFromString(<<<'HTML'
<!DOCTYPE html>
<html>
<body>
   <p>Hello, world!</p>
</body>
</html>
HTML);
echo $dom->saveHtml();
?>

The above example will output:

<!DOCTYPE html><html><head></head><body>
    <p>Hello, world!</p>

To load HTML without doctype, html, body elements use `LIBXML_HTML_NOIMPLIED` flag.<?php$html = <<<EOT<div class="row">    <div class="col"><h1 id="heading" class="col1-heading">Hello</h1></div>    <div class="col"><p class="paragraph">Hello world.</p></div>EOT;$doc = \DOM\HTMLDocument::createFromString($html, LIBXML_HTML_NOIMPLIED);echo htmlspecialchars($doc->saveHTML(), ENT_QUOTES);?>
