Walk from root through all children - change Attributes

[SarahTrees]

I come from simplehtmldom and have found your library, thank you very much for OpenSource!

I need to go through all the elements in parent-child order, recursively. I really like how easy it is to read and change attributes with this library.

$dom= new IvoPetkov\HTML5DOMDocument();
$dom->loadHTML('
<div class="row">
       <div class="col-6" data-attr="redcolumn">
              <div class="row">
                      <div class="col-10" data-attr="bluecolumn"><p>Text in a p</p></div>
              </div>
       </div>
</div>');

When starting I can start with
$dom->querySelectorAll('body > *'),
because my fragments are automatically integrated into a body by the library.
But how do I get all the direct divs which are included in my current elemts and not all the divs which are children of the children of the children ... ?

Per $childElement->querySelectorAll('*') I get all objects, not only the direct children - but I can very well read their attributes.
Per $childElement->childNodes I get the direct children, but I can't read their attributes, because the result is an object from the DOMParster, right? Is it possible to convert DomNode elements into HTML5DomNode objects?

Thank you for the support!

That's a really interesting situation. I expected that childNodes should handle that (because there is a DOMDocument::registerNodeClass call). Did you manage to find a solution?
