| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | XPath is known as a query language for XML documents. Translating an XPath formula to a deterministic tree automaton makes it simpler to evaluate it for an XML document. In this paper, we define a subclass of XPath, and propose a method for translating an XPath formula in that class to a deterministic selecting tree automaton with lookahead (DSTA$^B$). Our method translates a predicate part of a given XPath formula to a deterministic bottom-up tree automaton (DBTA) and translate the whole formula to a DSTA using the translated DBTA as a lookahead. Moreover, we improve the method by using a schema to eliminate useless rules for XML documents valid against the schema. Lastly we show the experimental result obtained by the tool implemented based on the proposed method. |
