Extensible Markup Language, a subset of the standard universal markup language, is a markup language used to mark electronic files to make them structured. In the electronic computer, the mark refers to the information symbol that the computer can understand. Through this kind of mark, the computer can process various information such as articles. It can be used to mark data and define data types. It is a source language that allows users to define their own markup language. It is very suitable for World Wide Web transmission, providing a unified method to describe and exchange structured data independent of applications or vendors. It is a cross-platform and content-dependent technology in the Internet environment, and it is also an effective tool for processing distributed structured information today. As early as 1998, W3C released the XML1.0 specification, using it to simplify the transmission of document information on the Internet.
