Abstract :
XML and XQuery have been widely accepted as the standard data representation and query language for web applications. When the input consists of a large amount of XML tokens, the main memory buffer requirement in XML stream processing can be significant, which might also lead to a significant CPU consumption due to the manipulation cost on the buffered data. To provide real-time responses, serious challenges in memory utilization are faced by the XQuery evaluation over XML streams. In many practical applications, XML streams are generated following a pre-defined semantic constraint such as the document type definition (DTD) and XML schema.
