<?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();

// Load some XML:
$success = $xml->LoadXml('<a><bbb><ccc><ddd>1</ddd><ddd><z>zzz</z></ddd><ddd>3</ddd></ccc></bbb></a>');

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

// This is what we have:

// <?xml version="1.0" encoding="utf-8"?>
// <a>
//     <bbb>
//         <ccc>
//             <ddd>1</ddd>
//             <ddd>
//                 <z>zzz</z>
//             </ddd>
//             <ddd>3</ddd>
//         </ccc>
//     </bbb>
// </a>

// The TagPath property is read-only property that returns the unique path to the
// node from the document root.

// For example:
$found = $xml->SearchForTag2($xml,'z');
if ($found == true) {
    // We found a node having the tag "z".
    // The TagPath property tells us the location in the document.
    $tagPath = $xml->tagPath();
    print $tagPath . "\n";

    // The tagPath is bbb|ccc|ddd[1]|z

    // If we to back to the document root, we can get to the given node via the tagPath.
    $xml->GetRoot2();
    print $xml->tag() . "\n";
    // The root tag is "a".

    // Follow the tagPath to the "z" node:
    $found = $xml->FindChild2($tagPath);
    print 'found = ' . $found . ', tag = ' . $xml->tag() . "\n";
    // We are now at "z".
