<?php

use Chilkat2\Xml;

$xml = new Xml();

$xml->LoadXml('<abc a="123" b="apple">Test</abc>');

// The UpdateAttribute and AddOrUpdateAttribute methods
// are identical.  Both will replace the attribute's value if it
// already exists, or insert a new attribute if it does not yet exist.

// Change the value of attribute "b" to "pear".
$xml->UpdateAttribute('b', 'pear');

// Because no attribute named "c" exists, UpdateAttribute
// will create it:
$xml->UpdateAttribute('c', 'orange');

// If an attribute's value is an integer, the AddToAttribute
// method may be called to update it by adding an integer value.
// For example, update the value of "a" to "130" by adding 7.
$xml->AddToAttribute('a', 7);

// Examine the result:
echo $xml->GetXml(), "\n";
