摘　　要：DOM是一种独立于语言和平台的XML解析模型。给出了支持DOM核心模型和多种DOM扩展规范的XML编辑器ONCEXMLEditor的实现。ONCEXMLEditor具有高效的XML验证和序列化性能,同时提供给用户多种功能,包括按需遍历文档、提供上下文感知的编写环境、实时纠错、灵活的装载和序列化机制等。描述了ONCEXMLEditor的体系结构及其实现核心算法,同时给出了XML文档有效性验证和装载及序列化的性能优化策略。DOM is a language and platform-neutral XML parsing model. Based on the implementation of DOM Core model and several DOM extended specifications, an XML editor ONCEXMLEditor is developed. Depending on its built-in efficient XML validation and serializing, ONCEXMLEditor can provide versatile capabilities for end-users, including giving custom-made traversal of XML documents, presenting context-aware editing, be capable of correcting errors immediately, along with flexible load and save mechanism. The architecture of ONCEXMLEditor is described and its essential algorithms is shown and the performance tuning policies for XML document loading and saving as well as XML validation are obtained.
