摘　　要：针对XML数据动态树型结构的特点,定义了内容操作集和结构操作集。在此基础上,提出一种基于此操作集的动态加锁协议以及锁模型,并证明了此加锁协议下的调度是可串行化调度,从而实现了XML原生数据库的事务并发控制。In accordance with the properties of dynamically changing tree-structured XML data, a set of content and structure operations are proposed. On the basis of this, an XML dynamic locking protocol （XL）, as well as a lock mode, is presented and it is proven that the schedule within the locking protocol mentioned above is serializability. As a result, the concurrency transaction for Native XML Databases is realized.
