随着无线传感器网络部署的增加和应用领域的拓宽，有效使用XML过滤和流查询引擎的机会越来越多。XML过滤引擎旨在提供对流XML编码数据的高效实时查询。本文详细分析了几个这样的引擎，重点是所涉及的技术、它们的功能、它们对XPath的支持以及它们的性能。我们的实验评估根据其属性确定哪个过滤引擎最适合处理给定的查询。这些指标对于建立动态过滤XML流的最佳方法非常重要。
As the deployment of wireless sensor networks increase and their application domain widens, the opportunity for effective use of XML filtering and streaming query engines is ever more present. XML filtering engines aim to provide efficient real-time querying of streaming XML encoded data. This paper provides a detailed analysis of several such engines, focusing on the technology involved, their capabilities, their support for XPath and their performance. Our experimental evaluation identifies which filtering engine is best suited to process a given query based on its properties. Such metrics are important in establishing the best approach to filtering XML streams on-the-fly.
