大型XML文档解析技术的应用与研究

Application and Research on Parsing Techniques of Large XML Document

随着XML应用的不断深入,XML文档快速解析技术的研究成为了当前的热点问题.在研究XML相关解析技术的基础之上,讨论大型XML文档的解析和处理问题,寻求实际问题的最优解决方案.首先,对目前较适合大型XML文档解析的两种技术(VTD-XML和SAX)做了简要的介绍,对其各自的优劣性进行了比较和分析;其次,针对作者正在研发的"核磁共振谱仪控制软件系统"中参数的XML设计和处理问题提出了具体的解决方案,验证了它们在处理大型文件时的可行性,并对它们的实际效果进行了对比分析;最后,针对以上两种解决方案的不足之处,提出了大型XML数据文件处理的其他解决方案.

With the continuous increase of the XML applications,the research of XML quickly parsing techniques have become a hot topic for current research. The paper mainly concerned the parsing and processing of the large XML document. Firstly,it discussed the techniques of XML parsing which fit for large XML document at present, such as, SAX and VTD-XML,it also analyzed and compared their respective advantages and disadvantages. Secondly,it made a solution to the question of XML processing encountered on project of NMR,compared the advantages and disadvantages of the two solutions, then draws a conclusion that both of them fit for the project. Furthermore,according to the faults of the two solutions mentioned previous;it proposed some other techniques fitting for large document.
