an XML file is an extensible Markup Language file;
XML itself is a Markup Language which shares some similarities to HTML.
Just like HTML, XML and XML files use tags; in XML's case, these tags are used to define, describe, structure, and nest data.
Furthermore, and contrary to HTML, each tag is not predefined, but is established by the users who generates the files.
Also, XML files are all about the information and data within a file and not about how to display the data or information.
