Change innerHTML of a php DOMElement [duplicate]

Answer 1

It seems that appendXML doesn't work always - for example if you try to append XML with 3 levels. Here is the function I wrote that always work (you want to set $content as innerHTML to $element):

function setInnerHTML($DOM, $element, $content) {
    $DOMInnerHTML = new DOMDocument();
    $DOMInnerHTML->loadHTML($content);
    $contentNode = $DOMInnerHTML->getElementsByTagName('body')->item(0)->firstChild;
    $contentNode = $DOM->importNode($contentNode, true);
    $element->appendChild($contentNode);
    return $elementNode;
}
