XML

XML, or Extensible Markup Language, is a flexible way to store and transport data. It uses plain text and tags (similar to HTML) to define elements, making it human-readable and machine-readable. XML allows users to create custom data structures, ensuring that information can be shared between different systems and applications easily. Commonly used in web services and data interchange, XML helps organize complex data in a straightforward format, allowing for efficient communication and processing while maintaining clarity and structure.
