<?php

if ($success != 1) {
    print $xml->LastErrorText . "\n";

    // Navigate to the Nth book 
    $xml->GetChild2($i);

    // Display the book title:
    print $xml->getAttrValue('title') . "\n";

    // Add a new integer attribute:
    // Should never fail..
    $xml->AddAttributeInt('bookId',$i);

    // Add a new unread="yes" attribute:
    $xml->AddAttribute('unread','yes');

    // Navigate back up to the parent:
    $xml->GetParent2();

}

// Navigate back to the document root:

// Save the updated document:
