XML has been popular as a means of sharing and distributing data due to its flexible and open architecture. XML-GL, a visual and intuitive query language for XML document, is easily used to search structures of XML documents and share information, since it represents the semantics of query and the structure of found documents visually. UML is used as a tool to analyze and design an object oriented system via defined notation and various diagrams. In this paper, we will propose a new object modeling method to map XML documents based on XML-GDM (a data model of XML-GL) to UML class diagrams. Thus, XML documents can be converted and stored and managed into object oriented data by an intuitive method. Applying the object oriented search method will improve the effectiveness in search of XML documents.
