XML (eXtensible Markup Language) is a versatile markup language designed to store and transport data. Unlike HTML, which is used to display data in web pages, XML is used to encode data in a format that is both human-readable and machine-readable. It provides a flexible way to structure and organize data, making it easier to share and manipulate across different systems and platforms.
XML uses a system of tags to define elements and attributes, which allows you to create a hierarchical structure for your data. This makes XML ideal for representing complex data structures, such as configuration files, data interchange formats, and more.
