The paper puts forward a query mode to by using XML query technology intraditional RDBMS of electric power corporation information system on the base ofstudying application of data query system and aiming at problem of information sharingand platform crossing. XML query uses XQuery language mainly to query XML datadocuments which abstracted from traditional RDBMS so that queried results can bedisplayed conveniently at client. On the base of deep study of XML query, XSLT andJavaScript technology were used in optimizing the result display and intelligible queryinterface was got. Through the query research to production departments' informationdata of electric power corporation, main functions of correlative data query wereimplemented.
