//  See Global Unlock Sample for sample code.

NSString *html = @"<html><body><p><b>Hello</b> World!<p>This is a test</body></html>";

//  Convert the above to XML
CkoHtmlToXml *h2x = [[CkoHtmlToXml alloc] init];

//  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;
NSLog(@"%@",[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:
NSLog(@"%@",[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:
NSLog(@"%@",[h2x ToXml]);

//  The resulting XML is:

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