| English Abstract: | Most type systems of statically typed XML processing languages are implemented based on regular expression types, where subtyping reduces to checking inclusion between tree automata, which is not efficient enough. The paper proposes the regular tree grammars with disjoint production rules and presents a subtyping method which is based on checking inclusion between regular expressions. The commonly used XML schema languages such as DTDs and XML Schemas can be described by the restricted grammars. The method works in a bottom-up way on the structures of type expressions. According to the regular expressions used in XML schema languages, different inclusion algorithms can be applied to this method. Experiments show the effectiveness of our method. © 2010 Springer-Verlag. |
