The DOMNamedNodeMap class

(PHP 5, PHP 7, PHP 8)

Class synopsis

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
8.5.0	Cloning a DOMNamedNodeMap object now fails.
8.0.0	The unimplemented methods DOMNamedNodeMap::setNamedItem(), DOMNamedNodeMap::removeNamedItem(), DOMNamedNodeMap::setNamedItemNS() and DOMNamedNodeMap::removeNamedItem() have been removed.
8.0.0	DOMNamedNodeMap implements IteratorAggregate now. Previously, Traversable was implemented instead.

Note:
Nodes in the map can be accessed by array syntax.

DOMNamedNodeMap::count — Get number of nodes in the map
DOMNamedNodeMap::getIterator — Retrieve an external iterator
DOMNamedNodeMap::getNamedItem — Retrieves a node specified by name
DOMNamedNodeMap::getNamedItemNS — Retrieves a node specified by local name and namespace URI
DOMNamedNodeMap::item — Retrieves a node specified by index
