While most researches for cyber counseling until now have been about counseling methods and the effects that teenagers utilize cyber counseling, there have been no efforts that store counseling contents, analyze them using features and technologies of web and use them effectively to guide students. Therefore, we propose a cyber counseling system that provides counseling information so that teacher may grasp students various interests and problems and thus helps to guide students. For this, we used XML. Since XML document can systematically create a structured information and represent a structure with meaningful information unit than the existing file-based information, it can be effectively used to manage, search and store documents. Thus, we implement a cyber counseling system using XML, which can effectively manage and represent the various analysis information of counseling.
