The XML file is designed to transmit and store data with the focus on the data content. HTML is designed to display data with focus on the appearance of the data. XML is just a text file that can be edited by any text editor in general. XML does not have a predefined label, and the label is case-sensitive. The label must also: Must have root element Attribute val
