Visual FoxPro

LOCAL loXml
LOCAL lnAutoCreate

*  Note: This example requires Chilkat v9.5.0.64 or later.
loXml = CreateObject('Chilkat.Xml')

loXml.Tag = "animals"

lnAutoCreate = 1

*  When the autoCreate argument equals 1, the UpdateAttrAt
*  method auto-creates the children as needed:
loXml.UpdateAttrAt("penguin",lnAutoCreate,"feature","flightless bird")
loXml.UpdateAttrAt("mammal|rodent|squirrel",lnAutoCreate,"feature","bushy tail")
loXml.UpdateAttrAt("mammal|rodent|rat",lnAutoCreate,"feature","long hairless tail")

*  Show the XML
? loXml.GetXml()

*  	<?xml version="1.0" encoding="utf-8" ?>
*  	<animals>
*  	    <penguin feature="flightless bird" />
*  	    <mammal>
*  	        <rodent>
*  	            <squirrel feature="bushy tail" />
*  	            <rat feature="long hairless tail" />
*  	        </rodent>
*  	    </mammal>
*  	</animals>
*  

*  Now update each node's "feature" attribute..
loXml.UpdateAttrAt("penguin",lnAutoCreate,"feature","black and white")
loXml.UpdateAttrAt("mammal|rodent|squirrel",lnAutoCreate,"feature","grey, red, or black")
loXml.UpdateAttrAt("mammal|rodent|rat",lnAutoCreate,"feature","brown, grey, white, or black")

? loXml.GetXml()

*  	<?xml version="1.0" encoding="utf-8" ?>
*  	<animals>
*  	    <penguin feature="black and white" />
*  	    <mammal>
*  	        <rodent>
*  	            <squirrel feature="grey, red, or black" />
*  	            <rat feature="brown, grey, white, or black" />
*  	        </rodent>
*  	    </mammal>
*  	</animals>
