Energy-Efficient XML Stream Processing through Element-Skipping Parsing

This paper proposes a scheme of energy-efficient XML stream processing through element-skipping parsing. Although parsing is one of the most computationally heavy part in the process of XML stream processing, existing techniques do not focus on the efficiency of XML parsing. To this problem, in our scheme, we propose element-skipping parsing where the parsing of such XML elements that do not contribute to the final query result is skipped with the coordination of XML parser and query processor. We show that the scheme is effective in reducing the execution time as well as energy consumption of stream-based XML query processor.
