Introduction

Wireless Markup Language (WML) is a markup language based on Extensible Markup Language
(XML) and was developed specifically for content and user interface for mobile device. WML is
a tag-based markup language designed after the model of HTML for Web content. The designers
of WML (and its companion scripting language, WMLScript) created an environment that demands
less memory and processing power from browsers than HTML and JavaScript.

!
Caution WML also includes features that tailor it for the relatively small display sizes of
today’s wireless devices .WML and HTML differ in significant ways.
Although WML strips some features from HTML and co-opts others, WML also incorporates
some powerful programming constructs not found in HTML like variables, tasks, and events.
WML implements a stricter tag syntax than HTML and includes a DTD for use with XML parsers.
The markup language of the WAP protocol for wireless Internet access. Pages written in WML
can be read and displayed properly by cell phones with a small screen where standard HTML
pages (the markup language used on most regular wide web pages) would produce an bad
output and might even be unviewable.
