The main goal of XForms is to make web forms design easier, allowing the developer to write less client-side scripting (or none at all), and less server-side code thanks to a feature-rich declarative approach.

Benefits of XForms include:

  • Clear separation between data captured and presentation (separation of concerns)
  • Flexible, structured XML-based data model: define your data model as an XML document, then create forms accessing the data
  • Built-in facilities for validation and data integrity based on XML Schema and/or assertions
  • Declarative approach requiring less / no scripting at all, in particular thanks to declarative events and actions
  • Ease of internationalization
  • Support for a variety of devices
  • W3C standard
  • Not tied to a particular platform or language such as Java or .NET
The key is to understand that you can't directly add data to an element the way you would with a plain HTML page. Instead, you need to put the information into the instance and then manipulate the XPath statement that specifies the contents of an XForms control.
