How to append HTML to a PHP DOMNode without encoding?

Inserting HTML into PHP DOMNode

To append HTML to an existing DOMNode without encoding, utilize DOMDocumentFragment::appendXML.

// DOM setup
$dom = new DOMDocument;
$dom->loadXML('<html><body/></html>');
$body = $dom->documentElement->firstChild;

// Append HTML fragment
$template = $dom->createDocumentFragment();
$template->appendXML('<h1>This is <em>my</em> template</h1>');
$body->appendChild($template);

// Output
echo $dom->saveXml();

Copy after login

Output:

<?xml version="1.0"?>
<html><body><h1>This is <em>my</em> template</h1></body></html>

Copy after login

Importing from Another DOMDocument

// Load another DOMDocument
$tpl = new DOMDocument;
$tpl->loadXML('<h1>This is <em>my</em> template</h1>');

// Import and append
$body->appendChild($dom->importNode($tpl->documentElement, TRUE));

Copy after login

Importing Malformed HTML

// Enable libxml error handling
libxml_use_internal_errors(true);

// Load and import HTML
$tpl = new DOMDocument;
$tpl->loadHtml('<h1>This is <em>malformed</em> template</h1></h2>');
$body->appendChild($dom->importNode($tpl->documentElement, TRUE));

// Disable libxml error handling
libxml_use_internal_errors(false);
