Recently, there has been growing interest in streaming XML data. Much of the work on streaming XML data has been focused on efficient filtering. Filtering systems deliver XML documents to interested users. The burden of extracting the XML fragments of interest from XML documents is placed on users. In this paper, we propose XTREAM which evaluates multiple queries in conjunction with the read-once nature of streaming data. In contrast to the previous work, XTREAM supports a wide class of XPath queries including tree shaped expressions, order based predicates, and nested predicates. In addition, to improve the efficiency and scalability of XTREAM, we devise an optimization technique called Query Compaction. Experimental results with real-life and synthetic XML data demonstrate the efficiency and scalability of XTREAM.
