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

Popis

class DOMNodeList {

DOMNode item ( int index )

}

Retrieves a node specified by index within the DOMNodeList object.

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

Index of the node into the collection.

Vrátené hodnoty

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

Príklady

Príklad 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";
}

?>
