<?php

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

$success = $xml->LoadXmlFile('add_attribute.xml');
if ($success != 1) {
    print $xml->lastErrorText() . "\n";
    exit;
}

//  Add an attribute  a="123" to the root node:
$xml->AddAttribute('a','123');

//  Navigate to the 1st child.  After calling FirstChild2,
//  "xml" now references the node with the tag "xyz".
$xml->FirstChild2();
$xml->AddAttribute('b','456');

//  Navigate to xyz's first child, which is the node having the
//  tag "mmm".
$xml->FirstChild2();
$xml->AddAttribute('c','789');
$xml->AddAttribute('d','000');

//  Revert back to the XML document root node
$xml->GetRoot2();

//  Examine the result:
print $xml->getXml() . "\n";
