Modern DOM library written in PHP for HTML documents. This library is an attempt to implement the [WHATWG's DOM specification][d] through a userland extension and encapsulation of PHP's built-in DOM. It exists because PHP's DOM is inaccurate, inadequate for use with any HTML, and extremely buggy. This implementation aims to fix as much as possible the inaccuracies of the PHP DOM, add in features necessary for modern HTML development, and circumvent most of the bugs.

## Limitations & Differences from Specification ##
The primary aim of this library is accuracy. However, due either to limitations imposed by PHP's DOM, by assumptions made by the specification that aren't applicable to a PHP library, or simply because of impractability some changes have needed to be made. These are as follows:
The primary aim of this library is accuracy. However, due either to limitations imposed by PHP's DOM, by assumptions made by the specification that aren't applicable to a PHP library, or simply because of impracticality some changes have needed to be made. These are as follows:
1. Any mention of scripting or anything necessary because of scripting (such as the `ElementCreationOptions` options dictionary on `Document::createElement`) will not be implemented.
2. Due to a PHP bug which severely degrades performance with large documents and in consideration of existing PHP software and because of bizarre uncircumventable `xmlns` attribute bugs when the document is in the HTML namespace, HTML elements in HTML documents are placed in the null namespace internally rather than in the HTML namespace. However, externally they will be shown as having the HTML namespace. Even though null namespaced elements do not exist in the HTML specification one can create them using the DOM. However, in this implementation they will be treated as HTML namespaced elements due to the HTML namespace limitation.
// HTMLCollections cannot be created from their constructors normally.
return Reflection::createFromProtectedConstructor(__NAMESPACE__ . '\\HTMLCollection', $this->innerNode, $this->innerNode->xpath->query(".//*[namespace-uri()='$namespace' and @href][name()='a' or name()='area']"));
}
protected function __get_plugins(): HTMLCollection {
# The plugins attribute must return the same object as that returned by the
# embeds attribute.
return $this->__get_embeds();
}
protected function __get_scripts(): HTMLCollection {
# The scripts attribute must return an HTMLCollection rooted at the Document node, whose filter matches only script elements.
// Because of how namespaces are handled internally they're null when a HTML document.
