' 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.
