  • The Difference Between XML and HTML
    • XML is not a replacement for HTML.
    • XML and HTML were designed with different goals:
      • XML was designed to transport and store data, with focus on what data is.
      • HTML was designed to display data, with focus on how data looks.
    • HTML is about displaying information, while XML is about carrying information.
