// 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.
