Ruby

require 'chilkat'

# Note: This example requires Chilkat v9.5.0.64 or later.
xml = Chilkat::CkXml.new()

xml.put_Tag("animals")

autoCreate = true

# When the autoCreate argument equals true, 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() + "\n";

# 	<?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..
xml.UpdateAttrAt("penguin",autoCreate,"feature","black and white")
xml.UpdateAttrAt("mammal|rodent|squirrel",autoCreate,"feature","grey, red, or black")
xml.UpdateAttrAt("mammal|rodent|rat",autoCreate,"feature","brown, grey, white, or black")

print xml.getXml() + "\n";

# 	<?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" />
