(PHP using ActiveX) Update an XML Attribute

Demonstrates how to update XML attributes.

The output XML is this:

<abc b="pear" c="orange" a="130">Test</abc>

Download Chilkat XML ActiveX

<?php

$xml = new COM("Chilkat.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:
print $xml->getXml() . "\n";
