<?php

$xml = new COM("Chilkat.Xml");

$success = $xml->LoadXmlFile('sample1.xml');
if ($success != true) {
    print $xml->lastErrorText() . "\n";
    exit;
}

//  Navigate to the "books" node:

$bFound = $xml->FindChild2('books');
if ($bFound == false) {
    print 'No books child found!' . "\n";
    exit;
}

$numChildren = $xml->NumChildren;

for ($i = 0; $i <= $numChildren - 1; $i++) {

    //  Navigate to the Nth book (we'll assume success...)
    $bFound = $xml->GetChild2($i);

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

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

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

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

}

//  Navigate back to the document root:
$xml->GetRoot2();

//  Save the updated document:
$success = $xml->SaveXml('modified.xml');
if ($success != true) {
    print $xml->lastErrorText() . "\n";
    exit;
}
