将树形数据结构用于最小化DOM 模型XML 编解码器的开发。在解析XML 文本时，基于Expat 解释器将XML 字符串构造成树

状结构；编码时构造DOM 树结构，采用非递归深度优先法遍历树，将其串行化成XML 串。本编解码器解决了国际化语言关键问题，是

一个通用、高效的工业级XML 应用支撑模块。-This paper designs a DOM liked tree data structure for developing a minimal DOM based eXtended Marked Language(XML) coding

and encoding module. When parsing XML text, based on expat, it puts the parsed content into the tree. When encoding, it constructs a DOM tree,

then use non-recursion depth-first method to access the tree and serialize it into XML text. This module also solves the key problem of international

language, and forms an universal, highly effective and industrial-level-reached basic module for XML application.
