DOMNodelist->item() -- Retrieves a node specified by index
Description
class
DOMNodeList {
DOMNode
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.
Return Values
The node at the indexth position in the DOMNodeList, or NULL if that is not a valid index.
Examples
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";
}
?> |
