Introduction

This represents immutable information about namespaces of an element. This decouples namespaces from attributes, which was incorrectly intertwined for the old DOM classes.

public ?string $prefix;
public ?string $namespaceURI;
public Dom\Element $element;
}

Properties

prefix

The namespace prefix of the attribute.

namespaceURI

The namespace URI of the attribute.

element
