use chilkat();

$xml = chilkat::CkXml->new();

# When the autoCreate argument equals 1, the UpdateAttrAt
# method auto-creates the children as needed:
$xml->UpdateAttrAt("penguin",$autoCreate,"feature","flightless bird");
$xml->UpdateAttrAt("mammal|rodent|squirrel",$autoCreate,"feature","bushy tail");
$xml->UpdateAttrAt("mammal|rodent|rat",$autoCreate,"feature","long hairless tail");

# Show the XML
print $xml->getXml() . "\r\n";

# 	<?xml version="1.0" encoding="utf-8" ?>
# 	<animals>
# 	    <penguin feature="flightless bird" />
# 	    <mammal>
# 	        <rodent>

# 	        </rodent>
# 	    </mammal>

# Now update each node's "feature" attribute..
