XML data have begun to be widely used in EC/EDI applications, digital libraries, and Web information systems. Such applications usually use a large number of XML data. First, we must allow users to retrieve only necessary portions of XML data by specifying search conditions to flexibly describe such applications. Second, we must allow users to combine XML data from different sources to produce new XML data. To this end, we will provide a query language for XML data called XQL. We have designed XQL, keeping in mind its continuity with database standards such as SQL and OQL although we don't stick to its strict conformity. In this paper, we describe the requirements for a query language for XML data and explain the functionality of XQL with its semantics based on set theory. Finally, we make brief comments on the implemetation of XQL.
