Demonstrates how to traverse all nodes in an XML tree.

Note: This example requires Chilkat v9.5.0.77 or greater.

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

Dim xml As New Chilkat.Xml

Dim success As Boolean = 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.
' 			</info>
' 		</animal>		
' 	</species>
'   </herd>
' </pig-rescue>

' The sbState is an object used to keep track of the current state of the traversal.
Dim sbState As New Chilkat.StringBuilder
While xml.NextInTraversal2(sbState) <> False

    Debug.WriteLine(xml.Tag)
    Debug.WriteLine(xml.TagPath)
    Debug.WriteLine("")
