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:
