Abstract

In an information processing apparatus, information is obtained from an internet and a template is selected from a plurality of templates in each of which at least one item is set to be extracted. Data corresponding to the item set in the selected template is extracted from the obtained information and is saved.

wherein said template selection means selects an appropriate template without requiring a selection by a user;

extraction means for searching currently displayed web page information for data corresponding to the respective attribute defined in the template selected by said template selection means, and extracting the searched out data from the currently displayed web page information; and

saving means for saving data extracted by said extraction means in the data field for the attribute corresponding to the extracted data, in the template selected by said template selection means.

2. An apparatus according to claim 1, further comprising template creation means for creating a template by defining at least one attribute to be extracted and adding the created template to the plurality of templates.

3. An apparatus according to claim 1, wherein said template selection means selects the template in accordance with a selection by a user.

4. An apparatus according to claim 1, wherein said template selection means selects a template containing an attribute corresponding to data in the obtained information as the appropriate template.

5. An apparatus according to claim 1, further comprising:

template display means for displaying the template selected by said template selection means with a data field corresponding to each of the attributes; and

extracted data display means for displaying the extracted data in the data field corresponding to the attribute of the extracted data.

6. An apparatus according to claim 1, further comprising:

extracted data list display means for displaying a list of names of the extracted data;

name specifying means for specifying a name in the list of names; and

extracted data display means for displaying the extracted data corresponding to the name specified by said name specifying means.

7. An apparatus according to claim 6, wherein said extracted data list display means displays the list of names in a tree structure in accordance with layers of an item.

8. An apparatus according to claim 6, wherein said name specifying means specifies a plurality of names and said extracted data display means displays a list of extracted data corresponding to the specified names.

9. An apparatus according to claim 6, wherein said saving means saves the extracted data in correspondence with a time when the data is extracted and said extracted data list display means displays the list of names in accordance with the time when the data is extracted.

10. An apparatus according to claim 1, further comprising sending means for sending the extracted data to an addressee.

11. An information processing method for processing web page information displayed by a browser, said method comprising the steps of:

selecting a template from a plurality of templates stored in a template memory,

wherein each of the plurality of templates defines at least one attribute of data to be extracted and a data field for the attribute;

wherein said template is selected without requiring a selection by a user;

searching currently displayed web page information for data corresponding to the respective attribute defined in the selected template, and extracting the searched out data from the currently displayed web page information; and

saving the extracted data in the data field for the attribute corresponding to the extracted data, in the selected template.

12. The method according to claim 11, further comprising creating a template by defining at least one attribute to be extracted and adding the created template to the plurality of templates.

13. The method according to claim 11, wherein said template is selected in accordance with a selection by a user.

14. The method according to claim 11, wherein said selected template contains an attribute corresponding to data in the obtained information as the appropriate template.

15. The method according to claim 11, further comprising:

displaying the selected template with a data field corresponding to each of the attributes; and

displaying the extracted data in the data field corresponding to the attribute of the extracted data.

16. The method according to claim 11, further comprising:

displaying a list of names of the extracted data;

specifying means for specifying a name in the list of names; and

displaying the extracted data corresponding to the name specified by said name specifying means.

17. The method according to claim 16, wherein said list of names is displayed in a tree structure in accordance with layers of an item.

18. The method according to claim 16, wherein a plurality of names are specified and said list of extracted data is displayed corresponding to the specified names.

19. The method according to claim 16, wherein said extracted data is saved in correspondence with a time when the data is extracted and said the list of names is displayed in accordance with the time when the data is extracted.

20. The method according to claim 11, further comprising sending the extracted data to an addressee.

21. An information processing program for controlling a computer to perform a method for processing web page information displayed by a browser, said method comprising the steps of:

selecting a template from a plurality of templates stored in a template memory,

wherein each of the plurality of templates defines at least one attribute of data to be extracted and a data field for the attribute;

wherein said template is selected without requiring a selection by a user;
