How to Save HTML of DOMDocument Without HTML Wrapper?

Problem Statement:

The code snippet below attempts to save the HTML content of a DOMDocument without the XML, HTML, body, and p tag wrappers, but it encounters issues when the content contains block-level elements.

$postarray['post_content'] = $d->saveXML($d->getElementsByTagName('p')->item(0));

Fix with loadHTML Options:

To resolve this issue, use the loadHTML() method with the following options:

$html->loadHTML($content, LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

These options instruct Libxml to parse the HTML without adding implied elements or a default doctype:

• LIBXML_HTML_NOIMPLIED: Turns off the automatic addition of implied HTML/body elements.
• LIBXML_HTML_NODEFDTD: Prevents a default doctype from being added when one is not found.

Result:

Using these options, saveHTML() will now output the HTML content without the unnecessary wrappers.

Note:

• Libxml 2.6 is required for LIBXML_HTML_NOIMPLIED.
• Libxml 2.7.8 is required for LIBXML_HTML_NODEFDTD.
