The structure of dom parsing tree is compatible with both specification of wap1 . x and wap2 . 0 , in the meantime , as html is subset of xml , waper can explore web contents through limited modification Waper的基于xmldom解析树的显示体系,不仅兼容于现有wap1 . x的格式标准,还适用于wap2 . 0的规范要求,使得waper具有较大的兼容性。
Note that you always list the operators functions first when processing the parse tree , because you need to know what the operator or function you are dealing with is before you know how to handle the arguments 注意,当处理解析树时,始终要首先列出操作/函数,因为在知道如何处理参数之前,需要知道将要使用哪个操作或者函数。
The algorithm of optimizing node ensures the continuity of parsing process and can add the node into the most appropriate position in the parsing tree . after many test and applications , the implementation has been ported in fact applications 设计中采用了最优节点的匹配算法,可以保证解析过程的连续性和错误处理能力,能够把节点以最佳的形式添加到解析树中。
