PHP DOM replace element with a new element

Question

I have a DOM object with loaded HTML markup. I\'m trying to replace all embed tags that look like this:

Answer 1

It's easy to find elements from a DOM using getElementsByTagName. Indeed you wouldn't want to go near regular expressions for this.

If the DOM you are talking about is a PHP DOMDocument, you'd do something like:

$embeds= $document->getElementsByTagName('embed');
foreach ($embeds as $embed) {
    $src= $embed->getAttribute('src');
    $width= $embed->getAttribute('width');
    $height= $embed->getAttribute('height');

    $link= $document->createElement('a');
    $link->setAttribute('class', 'player');
    $link->setAttribute('href', $src);
    $link->setAttribute('style', "display: block; width: {$width}px; height: {$height}px;");

    $embed->parentNode->replaceChild($link, $embed);
}

Edit re edit:

$dom->replaceChild($e, $a); // this line doesn't work

Yeah, replaceChild takes the new element to replace-with as the first argument and the child to-be-replaced as the second. This is not the way round you might expect, but it is consistent with all the other DOM methods. Also it's a method of the parent node of the child to be replaced.

(I used class not id, as you can't have multiple elements on the same page all called id="player".)
