XML () file, The difference between XML and HTML is that XML is designed to transmit and store data, and its focus is on data content. HTML is designed to display data, with focus on the appearance of data. HTML is designed to display information, while XML is designed to transmit information. Differences between XML and HTML Syntax: not all HTML tags need to appear in pairs. XML requires that all tags must appear in pairs. HTML tags are case-insensitive and XML is sensitive to size, it is case
