Abstract
In this paper we present a new XML-based query language for XML documents denoted XRL. This language expresses database conditions concerning the attributes and the structure of documents, as well as Information Retrieval conditions over their contents and their relevance. XRL queries can be stored into a XML repository and manipulated as any other XML document. In order to illustrate the usefulness of this language, we also describe some general guidelines of its current implementation, and present an example application. This application consists in a subscription/notification service of news articles, which are periodically retrieved from a digital library of newspapers according to the preferences of each user.
