<?php

// Build the 1st XML document:
// <x1>
//     <a1>1</a1>
//     <a2>2</a2>
//     <a3>3</a3>
// </x1>

$xml = new COM("Chilkat.Xml");
$xml->Tag = 'x1';
$xml->UpdateChildContent('a1','1');
$xml->UpdateChildContent('a2','2');
$xml->UpdateChildContent('a3','3');

// Build a 2nd XML document:

// <x2>
//   <b1>11</b1>
//   <b2>22</b2>
//   <b3>33</b3>
// </x2>

$xml2 = new COM("Chilkat.Xml");
$xml2->Tag = 'x2';
$xml2->UpdateChildContent('b1','11');
$xml2->UpdateChildContent('b2','22');
$xml2->UpdateChildContent('b3','33');

// We want to insert xml2 into xml to get this:

// <x1>
//     <a1>1</a1>
//     <x2>
//         <b1>11</b1>
//         <b2>22</b2>
//         <b3>33</b3>
//     </x2>
//     <a2>2</a2>
//     <a3>3</a3>
// </x1>

// Insert xml2 after "a1"

$index = $xml->TagIndex('a1');
if ($index < 0) {
    print 'a1 not found.' . "\n";
    exit;
}

$xml->InsertChildTreeAfter($index,$xml2);

print $xml->getXml() . "\n";

// The result is:

// <x1>
//     <a1>1</a1>
//     <x2>
//         <b1>11</b1>
//         <b2>22</b2>
//         <b3>33</b3>
//     </x2>
//     <a2>2</a2>
//     <a3>3</a3>
// </x1>

// Note: xml2 now points to the subtree within xml.
// For example, update "b3" and then see how it's updated within the merged document:
$xml2->UpdateChildContent('b3','33333333');

print $xml->getXml() . "\n";

// The result:

// <x1>
//     <a1>1</a1>
//     <x2>
//         <b1>11</b1>
//         <b2>22</b2>
//         <b3>33333333</b3>
//     </x2>
//     <a2>2</a2>
//     <a3>3</a3>
// </x1>
