<?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");

//  The XML used in this example contains the following:
//  This example will get the value of the "spay-neuter" attribute for each pig.

//  <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>
