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->LoadXmlFile('qa_data/xml/osszes.xml');

// The XML file we're loading contains this:

// <?xml version="1.0" encoding="iso-8859-2" ?>
// <EXAMPLE>
//     <OSSZES>
//         <ROW TYPE="INS">477953
//             <NUMBER>05107003972</NUMBER>
//         </ROW>
//         <ROW TYPE="INS">477954
//             <NUMBER>05107001342</NUMBER>
//         </ROW>
//         <ROW TYPE="INS">477955
//             <NUMBER>05107001342</NUMBER>
//         </ROW>
//         <ROW TYPE="INS">477956
//             <NUMBER>05107000017</NUMBER>
//         </ROW>**
//         <ROW TYPE="INS">477957
//             <NUMBER>05107002182</NUMBER>
//         </ROW>
//     </OSSZES>
// </EXAMPLE>
// 

// We wish to remove this subtree:

// <ROW TYPE="INS">477956
//     <NUMBER>05107000017</NUMBER>
// </ROW>

// Get another reference to the XML document.
// xml2 is a CkXml
$xml2 = $xml->GetSelf();

// Navigate to the node that is the root of the subtree to be deleted.
// In this case, we wish to find the node having tag "ROW" with content "477956"
$notUsed = $xml2->chilkatPath('OSSZES|/C/ROW,*477956*|$');

// Examine the xml2, it should be just the subtree.
print $xml2->getXml() . "\n";

// Now detach xml2 from the it's XML document.
// xml2 will now be it's own XML document.
$xml2->RemoveFromTree();

// Examine our original XML document.  The subtree is removed:
print $xml->getXml() . "\n";
