Примеры
Пример 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"; }
?>

<?php
foreach ($items as $item) { echo $item->nodeValue . "\n"; }
?>
