Dom\HTMLDocument: prototype.js like DOM-Traversal

Description

Hi,

I just started diving into the new DOM features that came with PHP 8.4, and wondered if it's possible (and/or in the focus of HTMLDocument) to add some of Prototype's DOM traversal and enumerable features. Prototype may have vanished from the web, but its intuitive traversal methods are to this day unmatched and made working on a HTML tree a breeze.

I've implemented this in PHP before, but it was a pain fighting against the quirks of DOMDocument, XML and the countless DOMNode subclasses, it felt very messy to begin with.

Now before I attempt to implement this again in userland with HTMLDocument: is there any chance to even consider such features, or is this out of focus?

Inizia leggendo le funzionalità del DOM di HTMLDocument introdotte in PHP 8.4 e confronta il comportamento di attraversamento ed enumerazione richiesto con le Prototype APIs collegate. Esamina poi l'implementazione esistente in userland in chillerlan/php-prototype-dom e usa la discussione dell'issue per stabilire se questo rientra in HTMLDocument e quale ambito di funzionalità verrebbe considerato completato.
