DOMNodelist::item — Retrieves a node specified by index
Retrieves a node specified by index within the DOMNodeList object.
If you need to know the number of nodes in the collection, use the length property of the DOMNodeList object.
Index of the node into the collection.
The node at the index th position in the DOMNodeList, or NULL if that is not a valid index.
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";
}
?>
Alternatively, you can use foreach, which is a much more convenient way:
<?php
foreach ($items as $item) {
echo $item->nodeValue . "\n";
}
?>
