A collation processing device has a document storage unit, axis transforming unit, automaton creating unit, and collating processing unit. The document storage unit stores document data having a hierarchical structure in which elements are sectioned by element identifiers. The axis transforming unit executes axis transformation on a search formula when the search formula is obtained, whereby the search formula concerned is transformed to a search formula constructed of child axes. The automaton creating unit identifies the type of element identifiers contained in the transformed search formula to create the automaton corresponding to the search formula concerned. The collating processing unit collates data contained in the document data with the automaton to output the data corresponding to the search formula.
