Demonstrates how to update XML attributes.

The output XML is this:

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

Chilkat PHP Downloads PHP Extension for Windows, Linux, MacOS, Alpine Linux, Solaris

<?php

// The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number.
// For example, if using Chilkat v9.5.0.48, then include as shown here:
include("chilkat_9_5_0.php");

$xml = new CkXml();

$success = $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".
$success = $xml->UpdateAttribute('b','pear');

// Because no attribute named "c" exists, UpdateAttribute
// will create it:
$success = $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";
