The file extension XML is defined as an Extensible Markup Language file which is used to create information formats that can be used across multiple platforms and the Internet. Extensible Markup Language is used to share data on the Internet, Local Area Networks, Intranets, and other types of communications in a common and consistent way.
Extensible Markup Language (XML) is a standard format which is similar to Hypertext Markup Language (HTML) and is a standard defined by the World Wide Web Consortium (W3C). Both languages are used to create web pages and use markup language to define the components of a web page. Hypertext Markup Language has limitations where Extensible Markup Language can extend the capabilities of web page components.
The file extension XML is categorized as a data file type which contains structured Extensible Markup Language in a plain text format. The file is used to describe hierarchal information for a wide variety of applications. The applications include but are not limited to web applications, databases, website components, web development, and more. Each description is surrounded by tags which facilitate the transmission of data across a variety of platforms. This enables data to be easily exchanged over the Internet and in many other instances.
