<?php

use Chilkat2\Xml;

// Note: This example requires Chilkat v9.5.0.64 or later.
$xml = new Xml();

$xml->Tag = 'animals';

$autoCreate = true;

// When the autoCreate argument equals true, the UpdateAttrAt
// method auto-creates the children as needed:
$xml->UpdateAttrAt('penguin', $autoCreate, 'feature', 'flightless bird');
$xml->UpdateAttrAt('mammal|rodent|squirrel', $autoCreate, 'feature', 'bushy tail');
$xml->UpdateAttrAt('mammal|rodent|rat', $autoCreate, 'feature', 'long hairless tail');

// Show the XML
echo $xml->GetXml(), "\n";

/*
 *     <?xml version="1.0" encoding="utf-8" ?>
 *     <animals>
 *         <penguin feature="flightless bird" />
 *         <mammal>
 *             <rodent>
 *                 <squirrel feature="bushy tail" />
 *                 <rat feature="long hairless tail" />
 *             </rodent>
 *         </mammal>
 *     </animals>

// Now update each node's "feature" attribute..
$xml->UpdateAttrAt('penguin', $autoCreate, 'feature', 'black and white');
$xml->UpdateAttrAt('mammal|rodent|squirrel', $autoCreate, 'feature', 'grey, red, or black');
$xml->UpdateAttrAt('mammal|rodent|rat', $autoCreate, 'feature', 'brown, grey, white, or black');
