摘　　要：XML正在成为Internet上数据描述和交换的标准.面向对象的方法具有很强的建模能力,例如继承、非单调继承、多态性、复杂数据结构等.将面向对象的特征引入到XML中,可以提高XML语言的建模能力.用继承扩展XML的模式语言DTD支持元素继承、非单调多重继承、重载、阻断、多态和冲突处理机制.XML-RL是基于高级数据模型的以规则为基础的XML查询语言,用面向对象的特征扩展XML-RL支持多态元素、包含元素.系统地给出面向对象的XML数据库的基于逻辑的语法和语义.XML is emerging as the dominant standard for information exchange over the Web. The modeling ability of object-oriented methods is strong, and data representation such as inheritance, nonmonotonic multiple inheritance, polymorphism, complex data structure, etc. Extending XML with some object-oriented features can improve the modeling ability of XML data model. DTD is extended with element hierarchy, multiple inheritance, overriding, blocking, polymorphism and conflict handling and XML-RL is extended with polymorphic element as well as inclusive element. XML-RL is a rule-based XML query language and it is based on high-level data model. The syntax and semantics of object-oriented XML database are described systemically.
