(PHP Extension) Demonstrates the ChilkatPath XML Method

Demonstrates how to use the ChilkatPath method. This example uses the XML sample file pigs.xml. The pigs.xml file contains this content:

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/pigs.xml');

// Get the content of the "species" node for the 1st animal:

$result = $xml->chilkatPath('animal|species|*');
// Output should be "pot belly pig"
print $result . "\n";

// Get the content of the "type" node for the 2nd animal:
// Indexing begins at 0.  Therefore, the 2nd direct child having
// the tag "animal" is at index 1
$result = $xml->chilkatPath('animal[1]|type|*');
// Output should be "House Pig"
print $result . "\n";

// Find the pig having the name "Nigel" and display the
// birth date.  To do this, we&apos;ll navigate to the node having
// tag="name" with the exact content "Nigel", then navigate up, 
// and finally navigate back down to the "birth" node:
$result = $xml->chilkatPath('/C/name,Nigel|..|birth|*');
// Output should be "June, 1991"
print $result . "\n";

// Navigate to the 1st animal&apos;s picture and print the filename,
// description, and caption.
// The "$" updates the caller&apos;s internal pointer to reference
// the node that is the result of evaluating the path.
// An empty string is returned for success, and a NULL/nil/0
// pointer (reference) is returned on failure.  
$result = $xml->chilkatPath('animal|picture|$');
if ($xml->get_LastMethodSuccess() != true) {
    print 'Failed to navigate to animal|picture.' . "\n";
    exit;
}

// Display the contents of the file/description/caption child nodes
print 'Picture Info:' . "\n";
print $xml->getChildContent('file') . "\n";
print $xml->getChildContent('description') . "\n";
print $xml->getChildContent('caption') . "\n";

// Return back to the root of the XML document:
