DOM change element content

Question

How does one change the element content with PHP DOM functions?

In depth... I've queried my element, modified attributes and now want to change the content of it, how can I do this?

Answer 1

Set the nodeValue property if you want to set text content of an element:

$el = $dom->getElementById('foo');
$el->nodeValue = 'hello world';

Note that this automatically escapes < and >, so you can't insert HTML like this. For that you'll have to do something like DOMDocument::createDocumentFragment:

$frag = $dom->createDocumentFragment();
$frag->appendXML('<h1>foo</h1>');
$el->appendChild($frag);
