摘　　要：传统数据挖掘是基于关系型数据库的,XML技术的出现,使它在短时间内成为表示和交换信息的标准,为数据挖掘提供了新的方法。对决策树、XML技术作了简要介绍,并对基于XML的数据挖掘基本过程进行了探讨研究,提出了一种决策树在XML数据库挖掘的分析模型。最后,通过一个实例来说明如何利用这个模型进行数据挖掘,并指明了今后的研究方向。Traditional data mining is based on relational database, XML （extensible markup language） technology has become as a standard for representing and exchanging information in a short period of time, a new data mining method is provided, the decision tree and XML technologies is introduced, as well as XML-based data mining basic process of the study. Then a novel model of the decision tree analysis based on the XML database is presented. Finally, through an example how to use this model for data mining is illustrated, and the direction of future research in the decision tree is pointed out.
