With the rapid advance of the Internet, management of structured documents such as XML documents has become more and more important (Marchiori, 1998). As a simplified version of SGML, XML is recommended by W3C (World Wide Web Consortium, 1998a; World Wide Web Consortium, 1998b) as a document description meta-language to exchange and manipulate data and documents on the WWW. It has been used to code various types of data in a wide range of application domains, including a Chemical Markup Language for exchanging data about molecules, the Open Financial Exchange for swapping financial data between banks and banks and customers, as well as a Geographical Markup Language for searching geographical information (Bosak, 1997; Zhang & Gruenwald, 2001). Also, a growing number of legacy systems are adapted to output data in the form of XML documents.
