A Direct Translation from XPath to Nondeterministic Automata
Since navigational aspects of XPath correspond to first-order definability, it has been proposed to use the analogy with the very successful technique of translating LTL into aut...

Using Regular Tree Automata as XML Schemas
We address the problem of tight XML schemas and propose regular tree automata to model XML data. We show that the tree automata model is more powerful that the XML DTDs and is clo...

Deterministic Automata on Unranked Trees
Abstract. We investigate bottom-up and top-down deterministic automata on unranked trees. We show that for an appropriate definition of bottom-up deterministic automata it is poss...

Reasoning about XML with temporal logics and automata
We show that problems arising in static analysis of XML specifications and transformations can be dealt with using techniques similar to those developed for static analysis of pr...
