How to Integrate HTML Templates into PHP DOMNodes While Preserving Raw HTML Content?

Integrating HTML Templates into PHP DOMNodes

Integrating HTML templates into existing PHP DOMNodes can be challenging, especially if you desire to preserve the raw HTML content.

Native PHP Solutions

PHP provides a few native methods to achieve this:

DOMDocumentFragment::appendXML: Appends raw XML data to a DOM DocumentFragment.

Example:

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

$template = $dom->createDocumentFragment();
$template->appendXML('<h1>

Copy after login

Output:

<html><body><h1>

Copy after login

DOMDocument::importNode: Imports a node from another DOMDocument.

Example for Importing from Another DOMDocument:

$tpl = new DOMDocument;
$tpl->loadXml('<h1>

Copy after login

DOMDocument::loadHTML: Loads HTML markup, triggering libxml's parser for potentially malformed HTML.

Example:

libxml_use_internal_errors(true);
$tpl = new DOMDocument;
$tpl->loadHTML('<h1>

Copy after login

Note:

In all these methods, using TRUE as the second argument to importNode imports the node and its entire subtree.
