The Technology And Application Of Converting SGML To XML

The SGML grew before the XML. It accumulated a lot of various DTD type data in various fields. As the unique rigor and limitation trait of SGML, there is a big bottleneck while it was applied to various fields of application. With its simple, open, efficient, scalable excellent performance, XML has gradually become the main carrier of the network data exchange and data processing. Transform the SGML format into XML format will take full advantage of existing SGML data. It can also accelerate the development of XML.This thesis did some research for the technology of transforming SGML to XML. It mainly uses a conversion program to transform the SGML to XML automatically. The program used two technologies for processing. One is the efficient identify regular expression matching replacement. The other is the XMLDocument class of the programming languages C Sharp(C #). The design platform is basely on Microsoft Visual Studio 2010, using the C# language code.The Conversion program is based on a specific production projects, design and coding according to the project’s specific needs. Design an automatic matching tag class, template rule processing class, node process class based on the XMLDocument class and additional procedures and functions for the conversion program. There are multiple spaces lost while testing the program. I found out a solution by detailed investigation and analysis. After a small batches testing and all the things are running right, applied the program to the specific production processes. The new method of production process is more than 10 times faster than the original production process. It significantly improved production efficiency. In the later several similar projects it also play an effective role.
