MXML

MXML, or "Macromedia XML," is a markup language used to create user interfaces for applications, primarily in Adobe Flex, which is now part of Adobe AIR. It enables developers to define the structure and behavior of their applications visually and easily by using XML-like syntax. MXML simplifies the process of designing rich internet applications by allowing developers to describe components, like buttons and text areas, without writing extensive code. It effectively allows for quick development and helps in building interactive web applications that run smoothly across different platforms.
