Numerous works to manage automatically the merge of the various versions of structured textual documents have been developed and correspond to the domain of "XML documents Diff & Merge". We propose in this paper, an alternative named interactive merge. This approach consists in not applying systematically the automatic merge but in keeping the transformation sequential and interactive. The objective is to propose to the user a list of operations associated with the original document, which he/she can confirm or not, according to the objective of the fusion and the detection of conflicts and inconsistencies.
