(no version information, might be only in CVS)

DOMNodelist->item() --  Retrieves a node specified by index

Descripción

class DOMNodeList {

DOMNode item ( int index )

}

Retrieves a node specified by index within the DOMNodeList object.

Sugerencia: If you need to know the number of nodes in the collection, use the length property of the DOMNodeList object.

Lista de parámetros

index

Index of the node into the collection.

Valores retornados

The node at the indexth position in the DOMNodeList, or NULL if that is not a valid index.

Ejemplos

Ejemplo 1. Traversing all the entries of the table

<?php

$doc = new DOMDocument;
$doc->load('book.xml');

$items = $doc->getElementsByTagName('entry');

for ($i = 0; $i < $items->length; $i++) {
    echo $items->item($i)->nodeValue . "\n";
}

?>

Alternatively, you can use foreach, which is a much more convenient way:

<?php

foreach ($items as $item) {
    echo $item->nodeValue . "\n";
}

?>
