// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

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

// Convert the above to XML
h2x := CkHtmlToXml_Create();

// 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
CkHtmlToXml_putHtml(h2x,html);
Memo1.Lines.Add(CkHtmlToXml__toXml(h2x));

// The resulting XML is:

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

//             </p>
//         </body>
//     </html>
// </root>

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

// Convert again to see the difference:
Memo1.Lines.Add(CkHtmlToXml__toXml(h2x));

// The resulting XML is:

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

//             <p>
//                 <text>This is a test</text>
//             </p>
//         </body>
//     </html>
// </root>

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

// Convert again to see the difference:
Memo1.Lines.Add(CkHtmlToXml__toXml(h2x));

// The resulting XML is:

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