    Beschreibung

    Retrieves a node specified by index within the DOMNodeList object.

    Tipp

    If you need to know the number of nodes in the collection, use the length property of the DOMNodeList object.

    index

    Index of the node into the collection.

    Rückgabewerte

    The node at the indexth position in the DOMNodeList, or null if that is not a valid index.

    Beispiele

    Beispiel #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";
    }

    ?>
