A Formalism for Navigating and Editing XML Document Structure

The use of XML has become pervasive. It is used in a range of data storage and data exchange applications. In many cases such XML data is captured from users via forms or transformed automatically from databases. However, there are still many situations where users must read and possibly write their own XML documents. There are a variety of both commercial and free XML editors that address this need. A limitation of most editors is that they require users to be familiar with the grammar of the XML document they are creating. A better approach is to provide users with a view of a document's grammar that is integrated in some way to aid the user.
