Why use XML

Suppose, communication is to be established between applications by sending messages. Application A wants to send first names and last name of students to application B and B on receiving the message should acknowledge it sending message “Accepted”. There are many different message formats in which application A can send message to application B. They won’t be able to properly communicate until a proper message structure is defined between application A and B.

Thus, XML defines a message structure for the data that needs to be communicated between different applications.
