基于正则表达式的总线数据过滤器组件设计

Data-Filter Component Design Based on Regular-expressions

介绍了一种基于正则表达式的网络数据过滤的应用程序设计方法。通过合理配置数据过滤程序,使用正则表达式进行XML数据验证,达到快速地匹配XML数据,实现提高数据过滤效率的目的。该数据过滤方法实现了数据过滤的灵活机制和组件复用,为数据过滤提供了模块化程序设计的途径,可作为网络信息安全监测系统应用程序设计的重要组件使用。

This article introduces a method of the program component based on the regular expressions.The configuration of data filter can match the XML data more easily and quickly,and it can improve the efficiency of data filter components.It uses a modularized program design method to achieve the data filter more neatly and it can be repeatedly used in the network information security monitor application in the programs.
