XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It is a flexible way to create common information formats and share both the format and the data on the World Wide Web, intranets, and elsewhere. XML is widely used in web development, web services, and database storage. It allows designers to create their own custom tags, enabling the definition, transmission, validation, and interpretation of data between applications and organizations.
