Answer 1

The problem is the call to replaceChild(). Rather than

$dom->replaceChild($nodeDiv, $nodePre);

use

$nodePre->parentNode->replaceChild($nodeDiv, $nodePre);

update

Here is a working code. Seems there is some issue with replacing multiple nodes (more info here: http://php.net/manual/en/domnode.replacechild.php) so you'll have to use a regressive loop to replace the elements.

$contents = <<hi

hello

STR; $dom = new DOMDocument; @$dom->loadHTML($contents); $elements = $dom->getElementsByTagName("pre"); for ($i = $elements->length - 1; $i >= 0; $i --) { $nodePre = $elements->item($i); $nodeDiv = $dom->createElement("div", $nodePre->nodeValue); $nodePre->parentNode->replaceChild($nodeDiv, $nodePre); }
