(PHP Extension) Traverse the XML Tree

Demonstrates how to traverse all nodes in an XML tree.

Note: This example requires Chilkat v9.5.0.77 or greater.

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");

// Use the NextInTraversal2 method to traverse all nodes in the XML tree rooted at the caller.

$xml = new CkXml();

$success = $xml->LoadXmlFile('qa_data/xml/twoPigs.xml');

// This is the XML traversed in this example:

// <pig-rescue>
//   <herd name="Cathy">
// 	<species name="pot belly pig">
// 	    <animal>
// 	        <name>Molly II</name>
// 	        <birth>February, 1998</birth>
// 			<in-date>January, 2000</in-date>
// 			<from>Middle Ave.</from>
// 			<gender spay-neuter="yes">F</gender>
// 			<info>Molly came from a place where an old, ill man had too many animals.
// 	              	The animals were seldom fed and rats would eat the newborn piglets.
// 	             	 When Molly was found at one week old, she was the only piglet of 
// 	              	her siblings who did not get stepped on by a cow. She is a sweet, 
// 	              	friendly pig who likes to hang out on Cathy's porch on the lounge 
// 	              	pad.
// 			</info>
// 		</animal>
// 	    <animal>
// 			<name>Nigel</name>
// 			<birth>June, 1991</birth>
// 			<in-date>August, 1991</in-date>
// 			<from>Breeder</from>
// 			<gender spay-neuter="no">M</gender>
// 			<info>
// 			 	Nigel was the first pig and the reason for the rescue in the
// 			 	first place. He is 13 now and doing well, but takes a number 
// 				of medications, as you can see below.
// 			</info>
// 		</animal>		
// 	</species>
//   </herd>
// </pig-rescue>

// The sbState is an object used to keep track of the current state of the traversal.
$sbState = new CkStringBuilder();
while ($xml->NextInTraversal2($sbState) != false) {

    print $xml->tag() . "\n";
    print $xml->tagPath() . "\n";
    print '' . "\n";

}

// Produces the following output:

// herd
// herd
// 
// species
// herd|species
// 
// animal
// herd|species|animal[0]
// 
// name
// herd|species|animal[0]|name
// 
// birth
// herd|species|animal[0]|birth
// 
// in-date
// herd|species|animal[0]|in-date
// 
// from
// herd|species|animal[0]|from
// 
// gender
// herd|species|animal[0]|gender
// 
// info
// herd|species|animal[0]|info
// 
// animal
// herd|species|animal[1]
// 
// name
// herd|species|animal[1]|name
// 
// birth
// herd|species|animal[1]|birth
// 
// in-date
// herd|species|animal[1]|in-date
// 
// from
// herd|species|animal[1]|from
// 
// gender
// herd|species|animal[1]|gender
// 
// info
// herd|species|animal[1]|info
//
