摘　　要：随着电子纸显示技术和网络数字内容的发展,手持移动阅读终端逐渐成为了一种必需品,而文档格式解析则是此类装置的核心。文档格式种类繁多,特点各异,而且各种格式版本也在不断变化,使得多格式解析引擎的构建成为关键技术。提出一种多格式解析引擎的系统架构,针对兼容多格式解析,实现扩展性和跨平台性,小屏幕阅读大幅面文档,提高解析显示速度等问题,给出了相应的解决方案。经在某商业公司的实验平台验证,该方案具有一定可行性。With the development of the E-paper technology, mobile-reader becomes a necessity, and the most important thing of it is format-parser. There are so many kinds of format, that have respective characteristics and many versions, so that designing a system contained multi-format parsers is the pivotal technology. A system scheme containing multi-format parsers was proposed. It could solve the pivotal problems： how to make multi-parsers compatible, realize the expansibility and the platform independence, read big pages on small screens, and improve the speed of display. This system that has been validated on the platform of a company was proved feasible.
