Dim success As Boolean = False

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

Dim xml As ChilkatXml
xml.Initialize

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.
