(PHP 5, PHP 7, PHP 8)

class DOMNamedNodeMap implements IteratorAggregate, Countable {

/* Properties */

public readonly int $length;

/* Methods */

public function count(): int

public function getIterator(): Iterator

public function getNamedItem(string $qualifiedName): ?DOMNode

public function getNamedItemNS(?string $namespace, string $localName): ?DOMNode

public function item(int $index): ?DOMNode

}

length: The number of nodes in the map. The range of valid child node indices is 0 to length - 1 inclusive.

Version	Description
8.0.0	The unimplemented methods DOMNamedNodeMap::setNamedItem(), DOMNamedNodeMap::removeNamedItem(), DOMNamedNodeMap::setNamedItemNS() and DOMNamedNodeMap::removeNamedItem() have been removed.
