DOMNodelist::item

(PHP 5, PHP 7)

Retrieves a node specified by index

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.

Returns:

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

Examples:

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:
