// Note: This example requires Chilkat v9.5.0.64 or later.
let xml = chilkat::Xml::new();

xml.set_tag("animals");

let auto_create = true;
// When the autoCreate argument equals true, the UpdateAt
// method auto-creates the children as needed:
let _ = xml.update_at("penguin", auto_create, "flightless bird");
let _ = xml.update_at("mammal|rodent|squirrel", auto_create, "bushy tail");
let _ = xml.update_at("mammal|rodent|rat", auto_create, "long hairless tail");

// Show the XML
println!("{}", xml.get_xml().unwrap_or_default());

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

// Now update each node's content..
let _ = xml.update_at("penguin", auto_create, "black and white");
