In order to deal efficiently with infinite regular trees (or other pointed graph structures), we give new algorithms to store such structures. The trees are stored in such a way th...
Many methods for XML processing have been proposed in the last few years. One popular approach is to process XML documents by using existing programming languages. Another popular...
Abstract. Tree-walking automata (TWAs) recently received new attention in the fields of formal languages and databases. Towards a better understanding of their expressiveness, we c...
