摘要
In a structured document search device, a condition for not appearing of an element specified by a search equation is obtained from structure information an added to a search automaton as an interrupt condition. When the interrupt condition is satisfied, the search automaton state transition is deleted. When all valid state transitions are absent, it is judged that no more element specified will appear even if analysis is continued and the analysis of the structured document is terminated. Thus, it is possible to extract enough elements specified by the search equation without searching the structured document to the end.
