大型XML文件的分割和动态加载研究

The Research of Large XML File's Partition and Dynamic Loading

作为交换数据的标准,分布式共享数据系统依赖于XML,但是处理大型XML文件会占用大量内存资源和网络传输带宽。文章在充分讨论了目前常用的操作XML的技术后,提出了一种基于SAX技术的大型XML文件的分割和动态加载的解决方法,并根据所提出的方法结合XML解析器进行了OCX控件封装,在实际中取得了良好的效果。

As exchange standard,XML is widely used in Distributed System.But when processing large XML file,mass memory and net bandwidth are used up.After analyzing two common XML processing technology DOM(Document Object Model)and SAX(Simple API of XML ),this paper designs a partition and dynamic loading method of large XML file based on SAX.Then it is been wrapped with XML parser of Microsoft and IBM as an OCX component.
