Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final xml = CkXml();

  xml.tag = 'world';

  // This example uses features introduced in v9.5.0.64
  xml.newChild2('north_america|united_states|california|san_francisco', 'Silicon Valley');
  xml.newChild2('north_america|united_states|california|san_diego', 'Birthplace of California');
  xml.newChild2('north_america|united_states|illinois|chicago', 'Windy City');

  print(xml.getXml());

  // Produces the following XML
  // 
  // 	<?xml version="1.0" encoding="utf-8" ?>
  // 	<world>
  // 	    <north_america>
  // 	        <united_states>
  // 	            <california>
