| Outline of Final Research Achievements |
In this study, the problem of correcting XSLT stylesheets according to schema updates is considered. As subsets of XSLT stylesheets, three classes of tree transducers UTT, UTTpat, and UTTpat,sel are defined. Firstly, it is shown that the problem becomes NP-hard for UTTpat and UTTpat,sel. Secondly, a polynomial-time algorithm for detecting XSLT rules affected by schema updates is constructed. Based on the algorithm, an algorithm for solving the problem is constructed. The algorithm is implemented in Java and experiments are conducted, which verifies the effectiveness of the algorithm.
