基于XML的多协议报文解析的方法与实现

Multi-protocol message parsing method and implementation based on XML

在现代工业控制领域中,尽管报文协议种类繁多,传统的报文解析技术仍存在着实时性低,对多协议报文解析效率低等缺点。针对上述问题,考虑到使用XML文档作为报文解析协议的优点,本文提出了一种基于XML的多协议报文解析方法,该方法利用XML文档作为报文格式描述文件,根据不同的报文格式编辑相对应的解析文档,采用报文解析器和解析协议文档相分离的形式对数据报文进行解析。实验结果表明,此方法很好的提高了报文的解析效率,同时实现了对多种不同格式报文的实时解析。

Although there are numerous message protocols in the field of modern industrial control, the real-time performance and the message parsing efficiency of traditional message parsing techniques are still poor. To solve the above problems, the advantages of using XML files as message protocols were taken into consideration. A multi- protocol message parsing method based on XML is presented in this study. This method uses the description of the document as a message format file. In this way, the message parser and resolution protocol document are respectively parsed according to their formats. Our results show that this method can significantly improve the efficiency of message parsing, and realize the real-time analysis of a variety of different format messages.
