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.
indexIndex of the node into the collection.
The node at the indexth position in the
DOMNodeList, or NULL if that is not a valid
index.
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";
}
?>
