  // See Global Unlock Sample for sample code.

  final html = '<html><body><p><b>Hello</b> World!<p>This is a test</body></html>';

  // Convert the above to XML
  final h2x = CkHtmlToXml();

  // By default, text formatting tags are dropped. Text formatting HTML tags are: b, font, i, u, br, center, em, strong, big, tt, s, small, strike, sub, and sup
  h2x.html = html;
  print(h2x.toXml());

  // The resulting XML is:

  // <?xml version="1.0" encoding="utf-8"?>
  // <root>
  //     <html>
  //         <body>
  //             <p>
  //                 <text>Hello World!</text>
  //             </p>
  //             <p>
  //                 <text>This is a test</text>
  //             </p>
  //         </body>
  //     </html>
  // </root>

  // To preserve text formatting tags, put the h2x instance into the mode where text formatting tags are not dropped:
  h2x.undropTextFormattingTags();

  // Convert again to see the difference:
  print(h2x.toXml());

  // The resulting XML is:

  // <?xml version="1.0" encoding="utf-8"?>
  // <root>
  //     <html>
  //         <body>
  //             <p>
  //                 <b>
  //                     <text>Hello</text>
  //                 </b>
  //                 <text> World!</text>
  //             </p>
  //             <p>
  //                 <text>This is a test</text>
  //             </p>
  //         </body>
  //     </html>
  // </root>

  // Call DropTextFormattingTags to put the h2x instance back in "drop" mode.
  h2x.dropTextFormattingTags();

  // Convert again to see the difference:
  print(h2x.toXml());

  // The resulting XML is:

  // <?xml version="1.0" encoding="utf-8"?>
  // <root>
  //     <html>
  //         <body>
  //             <p>
  //                 <text>Hello World!</text>
  //             </p>
  //             <p>
  //                 <text>This is a test</text>
