Inserting HTML into a PHP DOMNode without Encoding

When dealing with HTML in a PHP DOM environment, you may find the need to insert HTML content into an existing DOMNode. However, simply creating a new DOMElement or text node with the HTML code will result in the content being encoded, which may not be the desired result.

DOMDocumentFragment: AppendXML Method

To insert HTML content without encoding, you can use the DOMDocumentFragment class. This class allows you to create a fragment containing raw XML data. You can then append this fragment to your desired DOMNode.

Example:

// Create a DOM Document and load a minimal HTML structure
$dom = new DOMDocument;
$dom->loadXml('

'); $body = $dom->documentElement->firstChild; // Create a document fragment with the HTML template $template = $dom->createDocumentFragment(); $template->appendXML('

Importing from Another DOMDocument

If you want to import HTML from another DOMDocument, you can use the importNode method of the DOMDocument class.

// Create a new DOM Document for the template
$tpl = new DOMDocument;
$tpl->loadXml('<h1></h1>

Importing HTML using loadHTML

If you need to import potentially malformed HTML, you can use the loadHTML method of the DOMDocument class. This will trigger the HTML parser to attempt to correct any errors in the markup.

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

By utilizing these techniques, you can easily insert HTML content into a PHP DOMNode without content being encoded. This allows for more flexibility and control over the DOM manipulation process.
