  Reference numeral 1001 denotes a category name display field, which displays the name of the category selected in the product category selection list box 801 in FIG. A product name display field 1002 displays the names of products belonging to the product category. This information is obtained by extracting a product having <product> → <category ID> that is the same as <item ID> → <category ID> of the selected item XML from the product XML data 1300, and changing it to <product> → <product name>. The set value will be displayed. Reference numeral 1003 denotes an output product selection check box for setting whether to add product information to display data (HTML data).

  Reference numeral 1004 denotes an OK button. Upon receiving a notification that the button has been clicked on the information processing apparatus 102, the CPU 201 of the database server 101 receives the input information on the screen and displays it based on the received data. Product information 315 is created.

  Reference numeral 1005 denotes a cancel button. Upon receiving a notification that this button has been clicked on the information processing apparatus 102, the CPU 201 transmits a display information change screen 800 to the information processing apparatus 102, and performs processing via this screen. finish.

  Returning to the description of FIG. Thereafter, the CPU 201 determines whether a notification that the OK button 1004 or the cancel button 1005 of the display product setting screen 1000 shown in FIG. 10 displayed on the information processing apparatus 102 has been received is received (step S608). If it is determined that it has been received (YES in step S608), it is determined whether this is a notification that the OK button 1004 has been pressed or a notification that the cancel button 1005 has been pressed (step S609).

  If the CPU 201 determines in the determination process in step S609 that a notification that the OK button has been pressed has been received, the product information selected in the output column 1003 of the display product selection screen in the information processing apparatus 102 is acquired ( Step S610). Then, the selected product information acquired in step S610 is stored as display product information (step S611).

  8 is transmitted to the information processing apparatus 102 after step S611 is completed, or when it is determined in step S609 that the cancel button has been pressed in the determination process (step S609). S612).

  By displaying the display product information created by the above process when creating display information, multiple products belonging to the same product category can be displayed at once for products that create display information under the same conditions. Data can be created.

  FIG. 7 is a flowchart showing details of the HTML data (display information) creation process in step S408 of FIG. Note that programs and data for causing the CPU 201 to execute the processing according to the flowchart of FIG. 5 are stored in the HDD 204, which are loaded into the RAM 202 according to the control of the CPU 201, and are processed by the CPU 201 using the loaded programs and data. By performing the above, the database server 101 executes each process described below.

  First, the CPU 201 acquires display item XML data 1400 for which display data (HTML data) is to be created from the display item information DB 314 (step S701). Then, display product information corresponding to the display item XML data acquired in step S701 is acquired from the display product information 315 (step S702).

  1 is set to L which is a counter variable indicating the number of displayed products (step S703). Then, the processing from step S704 to step S714 is repeated for the display product.

  The CPU 201 acquires the product XML data 1300 corresponding to the product whose display order is the Lth from the product information DB 313 (step S704). Thereafter, the processes in steps S705 to S712 are repeated for the number of specification groups in the display item XML data (the number of specification group tags immediately below the basic item tag and the specification value information tag).

  The layout ID set for the specification group is acquired from the display item XML data (step S705). Then, the style sheet corresponding to the layout ID acquired in step S705 is acquired from the style sheet information DB (step S706).

  FIG. 16 is a diagram showing an example of file management information in the style sheet information DB.

  In the file management information, a layout ID 1601 and a file name (which may of course be file path information) 1602 are registered as registration items. The data configuration in FIG. 16 is an example, and it goes without saying that various item data are configured according to the use and purpose.

  Here, the style sheet used in the present invention will be briefly described. The style sheet used in the present invention is an XSLT style sheet. An xsl: for-each tag or the like is used for changing the number of display items, and an xsl: if tag is used for changing the display order. By using it, it is designed to be able to respond flexibly to the set conditions. In the process of applying the style sheet to the XML data, the CPU 201 performs a logical operation while referring to each value of the XML data, detects the data to be displayed from the XML data, and is used for display based on the detected data. HTML data is generated.

  FIG. 15 is a diagram for explaining a display form of variable items in the style sheet of the present invention. Each of the style sheets 1500-1 and 1500-2 has one or more display areas (1501, 1502-1, 1502-2, and 1503 in the figure). In the display area, an area where display items are determined and an area where display items can be variably set are set. For an area where the number of display items can be changed, a pattern in which the data is added in the horizontal direction, a pattern in which the data is added in the vertical direction, or a pattern in which both are performed can be set. This style sheet is set for each specification group.

  Returning to the description of FIG. 1 is substituted into M, which is a counter variable indicating the display area (display position) set in the style sheet acquired in step S706 (step S707). Then, the processes in steps S708 to S712 are repeated for each display area.

  Items displayed in the display area to be processed are acquired from the display item XML data, and a heading (output name) of each item is set (step S708). 1 is substituted into N, which is a counter variable indicating the display order of each item set as a display item in each display area of the style sheet (step S709). Then, the processes in steps S710 to S712 are repeated.

  With reference to the display item XML data, data (display group data) in which the display area (display position) is M and the display order is N is acquired. Then, by using the name of the data as a key, the item XML data corresponding to the display item XML data is referred to, and item information including the name is acquired. And the value of the said item is acquired from the product XML data corresponding to the product of the display order L (step S710). Thereafter, the data acquired in step S710 is added to the data being created so as to be in the display area and display order of the style sheet acquired in step S706 (step S711).

  After the process of step S711, the CPU 201 adds 1 to the variable N indicating the display order. If there is a data item to be displayed that has not yet been processed, the processing from step S710 is repeated.

  After the processing of steps S710 to S712 is completed for all display items, the CPU 201 adds 1 to the variable M indicating the display area (display position) (step S713). If there is a display area that has not yet been processed, the processing from step S708 is repeated.

  For all display areas, 1 is added to the variable L indicating the display product after the processing of step S708 to step S713 is completed. If there is a display product that has not yet been processed, the processing from step S704 is repeated.

  For all display products, after the processing from step S703 to step S714 is completed, a custom style sheet that is set to be applied to the created HTML data is acquired from the HDD 204, and the setting is applied to the created HTML data (step S715). The created HTML data is stored in the RAM 202 (step S716). Then, the HTML data created through this process is transmitted to the information processing terminal 102 and displayed.

  FIG. 11 is a diagram illustrating an example of a preview screen displayed on the display device 210 when the HTML preview button 804 is pressed on the information processing apparatus 102. On this screen, display processing of HTML data created through the processing of FIG. 7 is performed.

  Reference numeral 1101 denotes a custom style sheet selection combo box, in which a custom style sheet applied to the displayed HTML data is set. If the selection here is changed, the custom style sheet applied to the HTML data is changed, and the display is updated. A display product selection combo box 1102 can select a product to be displayed on the preview screen. If no product is selected here, all data to be displayed (set in FIG. 10) is set as preview target data.

  Reference numeral 1103 denotes an HTML data display field, in which HTML data created by the processing of FIG. 7 is displayed. In FIG. 11, a preview screen is created based on the display conditions of each item set in FIG. Therefore, display data is created in the product specification column in the order of the camera unit effective pixel, the digital zoom, the focal length of the lens sub-item, and the F value of the lens sub-item in accordance with the order 908 in FIG.
