This paper aimed at accept accurate output query results for the XQuery query over the XML Streams, and presents a solution based on XML Streams. Dynamically insert the update events into the XML Streams, constructed XML update Streams, so that we can receive continuous and precise results. XQuery language based on XPath queries use FLOWR expressions to achieve the complexity of queries on XML data...
