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

saveHTML can output a subset of document, meaning we can ask it to output every child node one by one, by traversing body.

$doc = new DOMDocument();
$doc->loadHTML('
Title...

...to be one of those crowning achievements...
');
// manipulation goes here

// Let's traverse the body and output every child node
$bodyNode = $doc->getElementsByTagName('body')->item(0);
foreach ($bodyNode->childNodes as $childNode) {
  echo $doc->saveHTML($childNode);
}

This might not be a most elegant solution, but it works. Alternatively, we can wrap all children nodes inside some container element (say a div) and output only that container (but container tag will be included in the output).
