(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 index
th 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:
