The design of user interfaces is a step which takes a long time. The automatic generation of these interfaces induces shorter durations. With this automatic generation, the UIDLs have appeared. They allow specifying an interface using a Description Language. A step which also takes a long time is the redesigning of the user interface to take into accounts users remarks. We propose to use the operators of the tree algebra with a UIDL as UsiXML which is structured as a tree to improve this step of design. These operators help the designer to modify the interfaces and to reuse parts of interfaces. We have estimated the saving of time in two case studies.
