PHP-Handbuch: Retrieves a node specified by index

Beschreibung

DOMElement DOMNodelist::item ( int $index )

Retrieves a node specified by index within the DOMNodeList object.

Tipp

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

Parameter-Liste

index: Index of the node into the collection.

Rückgabewerte

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

Beispiele

Beispiel #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";
}

?>
