[xml-soap-webservice] XML DL : 0: ML作为网络数据交换的标准技术，广泛应用于计算机软件．目前存储数据的主流手段是关系数据库，因此XML 文档与关系数据库之间必须进行转换。通过分析XML文档的层次结构，建立了XML文档树模型，并给出结点定义．依据 XML的BNF规则给出了元素与属性的正规表达式和相对应的状态转换图，设计了识别元素和属，|生的词法分析程序用于解析XML文档。提出了XML文档树到关系数据库存储的转换思想和算法，并结合实例给出转换后的关系表.-XML has become a standard technology in exchange ofa wide variety ofdata on web．It is widely applied in field ofcomputer software．However,relational technology is still the method to SaVe information．Therefore,XML document and relational database are transformed to each other．During analyzing thehierarchy ofXML document,XML document tree model is built and nodes ale defmed． Elements and attributes regular expression and state transition graph ale given ae∞rdmg toXML BNF, and lexjcal analyzer about identifying element and attribute is d骼i即ed in order to parse XML document． Conversion metllod and algorithm XML doeumerit tree to relational is developed,and relational tables are gained by all example．
