# 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>

# <mammal>
# <rodent>
# <squirrel feature="bushy tail" />
# <rat feature="long hairless tail" />
# </rodent>
# </mammal>

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