作为SGML的子集 ,元标记语言XML及其相关技术正得到越来越广泛的应用 .文档对象模型 (DOM )是一种平台无关、语言无关的标准接口 ,是XML、HTML文档互操作的基础 .首先论述了XML的应用前景和应用现状 ,然后提出了基于DOM的XML文档支持系统 ,系统为用户提供一套组件 ,用来完成XML文档的生成、表现、文档转换等工作 .系统同时提供DOM 1.0所定义的对外功能接口以支持Web的互操作 As a subset of SGML, meta-markup language XML and its related technologies are being more and more widely used.Document Object Model (DOM) is a platform-independent and language-neutral standard interface that is the basis of interoperability between XML and HTML documents First of all, it discusses the application foreground and application status of XML, and then proposes a DOM-based XML document support system, which provides users with a set of components to complete the generation, presentation, document conversion, etc. The system also provides DOM 1.0 defined external function interface to support Web interoperability
