XML vs. WML: What's the Difference?
Edited by Aimie Carlson || By Harlon Moss || Updated on October 11, 2023
XML is a markup language for encoding documents, while WML is a markup language tailored for mobile devices.
Key Differences
XML, or eXtensible Markup Language, is a language designed to store and transport data in a structured format. WML, or Wireless Markup Language, is a language developed for devices that operate over wireless communication networks.
XML is versatile and can be used in various applications such as web services, configuration files, and data storage. On the other hand, WML was specifically designed for small screens and limited bandwidths commonly found in mobile devices.
Both XML and WML have the ability to represent data in a structured manner. However, while XML is more generic and used in a wide range of applications, WML is narrowly focused on providing web content for wireless devices.
Another notable distinction is that XML has gained universal recognition and has a broad user community, while WML has become less prominent with the rise of more advanced mobile web technologies.
