# DOMNodelist->item()

(no version information, might be only in CVS)

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

## Description

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.

## 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:
