Ejemplos

Ejemplo 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"; } ?>
