We are addressing the efficient processing of continuous XML streams, in which the server broadcasts XML data to multiple clients concurrently through a multicast data stream, while each client is fully responsible for processing the stream. In our framework, a server may disseminate XML fragments from multiple documents in the same stream, can repeat or replace fragments, and can introduce new fragments or delete invalid ones. A client uses a light-weight database based on our proposed XML algebra to cache stream data and to evaluate XML queries against these data. The synchronization between clients and servers is achieved through annotations and punctuations transmitted along with the data streams. We are presenting a framework for processing XML queries in XQuery form over continuous XML streams. Our framework is based on a novel XML algebra and a new algebraic optimization framework based on query decorrelation, which is essential for non-blocking stream processing.
