XML (eXtensible Markup Language) is a markup language designed to store and transport data in a format that is both human-readable and machine-readable. Unlike HTML, which is primarily used to display data, XML focuses on describing and structuring data. It allows users to define custom tags, making it flexible for a wide range of applications, such as web services, configuration files, and data exchange between systems. XML is widely used in industries where structured data interchange is critical, such as finance, healthcare, and software development.
