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";
}
?>
|
