Remove parent element, keep all inner children in DOMDocument with saveHTML

Question

I\'m manipulating a short HTML snippet with XPath; when I output the changed snippet back with $doc->saveHTML(), DOCTYPE gets added, and HTML / BODY

Answer 1

tl;dr

requires: PHP 5.4.0 and Libxml 2.6.0

$doc->loadHTML("

test

", LIBXML_HTML_NOIMPLIED | LIBXML_HTML_NODEFDTD);

explanation

http://php.net/manual/en/domdocument.loadhtml.php "Since PHP 5.4.0 and Libxml 2.6.0, you may also use the options parameter to specify additional Libxml parameters."

LIBXML_HTML_NOIMPLIED Sets HTML_PARSE_NOIMPLIED flag, which turns off the automatic adding of implied html/body... elements.

LIBXML_HTML_NODEFDTD Sets HTML_PARSE_NODEFDTD flag, which prevents a default doctype being added when one is not found.
