An XML Document Transformation Algorithm Inferred from an Edit Script between DTDs

Finding an appropriate data transformation between two schemas has been an important problem. In this paper, assuming that an edit script between original and updated DTDs is available, we consider inferring a transformation algorithm, which transforms each document valid against the original DTD into a document valid against the updated DTD, from the original DTD and the edit script. We first show a transformation algorithm inferred from a DTD and an edit script. We next show a sufficient condition under which the transformation algorithm inferred from a DTD D and an edit script is unambiguous, i.e., for any document valid against D, elements to be deleted/inserted can unambiguously be determined. Finally, we show a polynomial-time algorithm for testing the sufficient condition.
