XML (eXtensible Markup Language) is a text-based data format used to transport data within a specific structure. It has a format that is readable and understandable by both humans and computers. XML organizes data hierarchically using a specific tag structure.
XML is commonly used for organizing, storing, transporting, and modifying data. It is particularly used in data interchange and data structure definition areas. XML is widely used in web services, configuration files, documentation processes, and database content transfers.
