The <go> tag has a central role in WML. The user agent can change cards by the tag. This tag can call either a WMLScript function or move to another card of the WML deck. In the following example, clicking the Help option triggers a switch to card card1_help:

To help you validate your wml, we have used The Microsoft's XML parser to create a wml validator. Paste your wml in the text area, and validate it by pressing the validate button.

There are several Usability issues emerging with respect to delivering content to wireless devices. By far the most important of these is the recommendation that User Interfaces must be consistent in order to promote Usability. Consistency relies on standards or guidelines and the presentation of a coherent guideline compliant application. However, with current portal and content aggregation strategies Usability is being sacrificed in order to facilitate time to market.

Wireless Markup Language (WML) is an XML-defined markup language for creating and serving up wireless-friendly information and applications for WAP (Wireless Application Protocol) enabled devices and browsers.

The links in the "Start tag" column points to more useful information about the specific tag. It also cover attributes of the specific tag and code examples.

This Library dynamically translates HTML pages to WML (WAP protocol) pages. WML, which is intended for hand held devices, is different from HTML and introduces a number of conversion issues. The library provides a simple C++ API to read a HTML file and generate an equivalent WML file. If the HTML file is longer than the acceptable WML length, the converter splits the WML file into multiple files and links them together with hyper links.

With the explosion in alternative browsing devices, portals need to present more than one representation of their content. Didier Martin demonstrates how to build your own XML-driven portal."

As promised, we return to our HTML/WML portal project to demonstrate creating the WML side of the portal using XSLT, XLink, and XInclude."

HDML is still a widespread language for marking up mobile phone content. Didier Martin introduces us to the differences between HDML and WML, and shows how HDML can be created from XML."
