一种新型嵌入式浏览器解析布局器的实现

A New Parse-Layout Engine Implemented in Embedded Browsers

现有的嵌入式浏览器在解释和显示页面模块的实现策略上往往大相径庭。本文通过分析比较现有几种主要机制的优缺点,提出并实现了页面分块显示机制,将一个页面块中的显示信息用一个二叉树结构存放;另外,通过生成和遍历页面信息二叉树,将大多数浏览器中的语法分析、语义分析、页面显示步骤整合在一起,进一步提高了浏览器运行效率和响应速度。

The existing embedded browsers behave differently in the implementation tactics of the modules for parsing and displaying Web pages. By analysing and comparing the merits and demerits of the existing several mechanisms, the paper puts forth and implements a mechanism of Web page division, and stores the dispaly information of Web page blocks in a bintree. In addition, by generating and traversing the syntax parsing, semantic parsing and Web page display in most brows- ers are integrated to enhance the efficiency and responsive speed of the browsers.
