DATA ACQUISITION PROGRAM, DATA ACQUISITION METHOD AND DATA ACQUISITION DEVICE

A data acquisition program, a data acquisition method, and a data acquisition apparatus, which enable data of a targeted part to be extracted and output even if specific tag information is not available, are provided. The data acquisition program causes a computer (100) to execute a process of: identifying a position of a part to be extracted in a document that is associated with a specific URL and includes structural information of tags, the position being on a hierarchical structure of the tags included in the document; and allowing the position on the hierarchical structure to be registered (131). Further, the data acquisition program causes the computer (100) to execute a process of: periodically or non-periodically accessing the document associated with the specific URL (132); and extracting and outputting data corresponding to the registered position on the hierarchical structure of the tags (133, 134).
