PHP

Retrieves a node specified by index


DOMNodelist::item

(PHP 5)

DOMNodelist::item Retrieves a node specified by index

Description

DOMNode DOMNodelist::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.

Parameters

index

Index of the node into the collection.

Return Values

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

Examples

Example #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";
}

?>

The above example will output:
