Change innerHTML of a php DOMElement [duplicate]

Answer 1

I think the best thing you can do is come up with a function that will take the DOMElement that you want to change the InnerHTML of, copy it, and replace it.

In very rough PHP:

function replaceElement($el, $newInnerHTML) {
    $newElement = $myDomDocument->createElement($el->nodeName, $newInnerHTML);
    $el->parentNode->insertBefore($newElement, $el);
    $el->parentNode->removeChild($el);

    return $newElement;
}

This doesn't take into account attributes and nested structures, but I think this will get you on your way.
