XForms
Welcome to the XForms Tutorial and Cookbook Wikibook!

XForms is a World Wide Web Consortium recommendation for creating web forms and web applications. It's easy to learn, provides a rich user experience and does not require you to learn JavaScript.

A printable version of XForms is available. (edit it)

There are many different implementations of XForms and this cookbook is designed to work with any of them. A list of implementations is available on the W3C website.

This is a collaborative project and we encourage everyone who is using XForms to contribute their complete working XForms examples. All submissions must be licensed under the Creative Commons Attribution-ShareAlike 2.5 license.

Note: many of the examples in this wikibook still use the "nodeset" attribute for binding rules, groups and repeats. Most XForms systems (Orbeon and betterForm) now use the "ref" attribute and may no longer support the older "nodeset" attributes. XSLTForms 1.0RC does not allow @ref instead of @nodeset but builds since rev.559 do support @ref where @nodeset was previously used. We will be updating the examples accordingly.
