How Can I Save a DOMDocument's HTML Content in PHP Without the Default HTML, Body, and P Tags?

Save HTML of DOMDocument Without HTML Wrapper

In your PHP function, you are attempting to save the contents of a DOMDocument without the enclosing , body, and

tags. However, saveXML() tends to add these wrappers when used with getElementsByTagName('p').

Alternative Solution for PHP 5.4 and Above

With PHP 5.4 and Libxml 2.6 or higher, you can utilize the loadHTML() function with additional options to prevent implied HTML elements and doctype:

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

Using these options, saveHTML() will not produce the unwanted wrappers.

Explanation of Options:

• LIBXML_HTML_NOIMPLIED: Disables adding automatic implied html and body elements.
• LIBXML_HTML_NODEFDTD: Prevents creating a default doctype if none is present in the input content.

Additional Notes:

• Documentation for Libxml parameters can be found here.
• Note that while loadHTML documentation mentions Libxml 2.6 as a requirement, LIBXML_HTML_NODEFDTD became available in Libxml 2.7.8, and LIBXML_HTML_NOIMPLIED was available from Libxml 2.7.7 onwards.
