public function evaluate(string $expression, ?DOMNode $contextNode = null, bool $registerNodeNS = true): mixed

public function query(string $expression, ?DOMNode $contextNode = null, bool $registerNodeNS = true): mixed

public static function quote(string $str): string

public function registerNamespace(string $prefix, string $namespace): bool

Версія	Опис
8.4.0	It is no longer possible to clone a DOMXPath object. Doing so will result in an exception being thrown. Prior to PHP 8.4.0 this resulted in an unusable object.
8.0.0	The `registerNodeNamespaces` property has been added.
