XML stands for eXtensible Markup Language. It is a text-based format for storing and transporting data that is self-descriptive and independent of software and hardware.

XML is used for mainly these purposes:

• Data transfer: XML can be used to create APIs that allow different applications to exchange data over the Internet.
• Formatting documents: XML can be used to define the structure and appearance of documents, such as web pages, ebooks, and reports.
• Creating layouts: XML can be used to describe the layout of graphical user interfaces, such as menus, buttons, and windows.
