Object-oriented representation for XML data

XML is a new standard for representing and exchanging data on the Internet. How to model XML data for Web applications and data management is a hot topic in the XML research area. The paper presents an object representation model for XML data. A set of transformation rules and steps are established to transform DTDs, as well as XML documents with DTDs, into this model. This model capsulizes elements of XML data and manipulation methods. This pure object oriented model considers the features and usage of XML data and is suitable for Web applications as well as XML data management. DTD-Tree is defined to represent DTD and describe the procedure to use transformation rules. DTD-Tree can also be used as a logical interface for DTD processing.
