XML DOCUMENT SUPPORT SYSTEM BASED ON DOM
Jing Li · 2000
As a subset of SGML, meta markup language Extensible Markup Language (XML) and related technologies are used more broadly. Document Object Model(DOM) is the basis of the implementation of document interoperation,it is a set of platform independence and language independence interfaces. First, the paper discusses the applied trend and current situation of XML , then an XML Document Support System Based on DOM is addressed. The system is composed of 2 parts: Kernel component and User component. Kernel component is divided into 3 entities: Parser, Document Access and XSL Format. Parser analyzs input XML or DTD file and generates internal document object tree like data organization which is maintenanced by Document Access. Standard interfaces defined by DOM version 1.0 are implemented in Document Access. For the lack of definition on DTD operation, we also provided the interfaces for DTD. XSL Format is used to give XML document different presentations such as display and print. User component provides users a set of components to accomplish the creation of XML document, the presentation of XML document, and the conversion between different document format. Because the architecture is component faced, users can choose required function flexiblely.
