Data acquisition method, data acquisition apparatus, and recording medium

A non-transitory computer-readable recording medium storing a data acquisition program that causes a computer to execute a process comprising:

• displaying a document that is associated with a specific URL and described in HTML format or displaying a source of the document;
• receiving a selection of a part to be extracted that is included in the displayed document or the displayed source of the document;
• identifying a hierarchy of a tag corresponding to the received part to be extracted;
• registering the identified hierarchy as information identifying a position of the part to be extracted;
• and
• accessing periodically or non-periodically the document associated with the specific URL, and extracting and outputting data corresponding to the registered hierarchy.

A data acquisition method comprising:

• displaying a document that is associated with a specific URL and described in HTML format or displaying a source of the document, by a processor;
• receiving a selection of a part to be extracted that is included in the displayed document or the displayed source of the document, by the processor;
• identifying a hierarchy of a tag corresponding to the received part to be extracted, by the processor;
• registering the identified hierarchy as information identifying a position of the part to be extracted, by the processor;
• and
• accessing periodically or non-periodically the document associated with the specific URL, and extracting and outputting data corresponding to the registered hierarchy, by the processor.

A data acquisition apparatus comprising:

• a processor configured to:
• identify 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 allow the position on the hierarchical structure to be registered;
• and
• periodically or non-periodically access the document associated with the specific URL, and extract and output data corresponding to the registered position on the hierarchical structure of the tags, wherein when data corresponding to the position on the hierarchical structure of the tags, the data having been extracted and registered in the past, is different from data corresponding to the position on the hierarchical structure of the tags, the data having been extracted and registered this time, the processor is configured to output information indicating that the data have changed.

A data acquisition apparatus comprising:

• a processor configured to:
• identify 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 allow the position on the hierarchical structure to be registered;
• and
• periodically or non-periodically access the document associated with the specific URL, and extract and output data corresponding to the registered position on the hierarchical structure of the tags, wherein when a plurality of positions of the part to be extracted have been registered for the document, the processor is configured to perform output according to the number or rate of data matching past data, in data corresponding to the plurality of positions.

A data acquisition apparatus comprising:

• wherein the processor is configured to
• display a document that is associated with a specific URL and described in HTML format or displaying a source of the document;
• receive a selection of a part to be extracted that is included in the displayed document or the displayed source of the document;
• identify a hierarchy of a tag corresponding to the received part to be extracted;
• register the identified hierarchy as information identifying a position of the part to be extracted;
• and
• access periodically or non-periodically the document associated with the specific URL, and extracting and outputting data corresponding to the registered hierarchy.
