Abstract

With the rapidly increasing popularity of XML, an effective method to transmit XML data over wireless broadcasting environments is urgently required. In this paper, a novel XML data streaming method for wireless broadcasting environments, is proposed. An XML stream is organized to enable a selective access scheme for simple XPath queries, by borrowing the path summary technique, which was originally devised for indexing semi-structured data. In order to utilize structure information as an XML stream index, the structure information and text values of an XML document are separated. In experimental results, the proposed method demonstrates superior performance over previous approaches with regard to both access and tuning time.
