As HTML forms show inconsistency with XML based internet standards, XForms is proposed as a new standard of an internet form language. As XForms separate the data and logic of a form from its presentation, we can use XML for data transport and any XML host language for data display, such as XSL. However, it is expensive to create XForms and/or XSL codes since it depends on the type of XML data.

In this paper, we present an automatic generation method of XForms codes from the document type information. In order to find a user model, we adopt repetitive data update model, where user can add/delete only the repetitive parts of XML data. Using this model, we generate an XForms code in terms of repeating structure of XML data based on DTD. We present the user model and generation algorithm with the discussion on its applications.
