See more XML Examples

Demonstrates how to traverse all nodes in an XML tree.

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

Visual FoxPro

LOCAL lnSuccess
LOCAL loXml
LOCAL loSbState

lnSuccess = 0

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

loXml = CreateObject('Chilkat.Xml')

lnSuccess = loXml.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.
loSbState = CreateObject('Chilkat.StringBuilder')
DO WHILE loXml.NextInTraversal2(loSbState) <> 0

    ? loXml.Tag
    ? loXml.TagPath
    ? ""

ENDDO

*  Produces the following output:

*  herd
