To reduce the processing load for processing structured data pieces in different representation forms, a path correspondence table storage area stores a path correspondence table having a correspondence between first position information for locating an item of a first structured data piece and second position information for locating the item of a second structured data piece, having a different representation form from that of the first structured data piece and corresponding to the item located by the first position information. If the first position information is specified, and a request for obtaining information relating to an item in the second structured data piece is received, a path converting section uses the path correspondence table to convert the first position information to the second position information and obtain the information relating to the item from the second structured data piece stored in a structured data storage area.
