At present,the Apriori algorithms realized by the XQuery language are basically used for mining the single XML documents.But regarding the reality in XML documents,in some situations related data are deposited in several documents which have no inevitably relations among them.At this point,several documents have to be simultaneously taken into consideration in order to mining the information.In view of the question how to mining several XML documents,to improve the Apriori algorithms based on the XQuery language,the collection function is introduced which can realize the visit to the composition set node of several XML documents.Then it can mining the association rules from several XML documents.Last,the experiment verifies its feasibility and efficiency,make it has the same effect as mining the single XML documents.
