    // The XML used in this example contains the following:

    // 			<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.
