This paper proposed a strategy to support parallel modification to XML data in distributed environments.With this approach different users were able to simultaneously modify different portions or the same portions of the same XML data,and decentralized management of update operations was supported in which a user could perform his privileges and verify the correctness with the digital signature technology and without interaction with the data server.Dynamic users and dynamic policies were supported which means a user might join in or drop out of during the modify process and the privilege of a user over some portions of a XML data might be changed.
