Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information providing service using an HTML file described in a description language HTML, and more particularly to a link destination control method and system of a browser.

[0002]

2. Description of the Related Art Information published on the Internet is referred to by using a browser such as Netscape or Mosaic. The information is created using a description language called HTML, and in HTML, it is possible to set a link object having address information for linking to other information.

[0003] As described in Hypertext Markup Language-2.0 (RFC1866), in the conventional technique, only one fixed link destination can be set in an HTML file in a link object. For this reason, the browser cannot change the link destination from one link object according to the operation status (condition).

[0004]

In electronic commerce and the like, even when the same link object is designated by a user, a link destination is automatically selected in accordance with a condition such as a user's use history or preference, and a link destination is selected for each user. It is convenient to be able to provide suitable different information.

An object of the present invention is to control a link destination of an HTML file browser in which a plurality of link destinations are made to correspond to a link object which is a text or a picture in which a link destination in an HTML file is set and a link destination is automatically selected according to a condition. It is to provide a method and a system.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a plurality of link destinations set in advance in a single link object of an HTML file in the HTML file or in another file or storage device referred to by a browser. The main feature is that the browser has a function of selecting one optimal link destination. It differs from the conventional technology in that a browser selects an optimal link destination according to conditions.

In the present invention, a plurality of link destinations are described together with link conditions in a link object corresponding portion in an HTML file, or a condition for selecting a link destination is described in a variable form. Next, the browser refers to another file in which the link condition or the link destination address is described, and when a plurality of link destinations are set together with the link condition in the link object corresponding portion, the link destination suitable for the condition. To delete other link destinations, or, if the selection criteria for link destinations are set by variables, set one link destination in the link object portion, and use the conventional format, ie, one link HT with one link destination set for the object
Format into an ML file. Thereafter, links to other information are set in exactly the same procedure as in the conventional browser.

[0008] Thus, it is possible to automatically select a link destination from a plurality of link destinations specified in the link object according to conditions.

[0009]

FIG. 1 is a block diagram for explaining a link destination control system of an HTML file browser according to the present invention. 1 is an HTML file browser, 2 is a link destination determining unit, 3 is an HTML interpreting unit, 4 is an HTML processing unit,
5 file reading units.

In the HTML file browser 1, a URL which is a protocol name, a server name, or a directory name input from the keyboard 10 is input to the HT via the input unit 8.
The HTML file 6 is interpreted by the ML interpreting unit 3 and read from the server having the URL using the file reading unit 4. The read HTML file 6 is interpreted by the HTML interpreter 3 to shape the screen, and displayed on the display 12 through the output unit 9. Next, a specific first embodiment will be described with reference to the drawings.

When a link object of an HTML file already displayed on the display 12 is designated by using the mouse 11, the link destination set in the link object is entered via the input unit 8 into the HTML interpreting unit 3.
The new HTML file 6 is read into the file reading unit 5 from the link destination set in the link object, and is passed to the HTML interpreting unit 3. FIG. 2 shows the contents of the HTML file 6 read at this time.

The HTML interpreter 3 generates an HTML file 6
Tag indicating that multiple link destinations are set from within <
Search for <SOMELINK> and if <SOMELINK>
If there is a tag, the link destination determination unit 2 is started. The link destination judgment unit 2 refers to the condition file 7 and
Is described as JOKEN = 1, the link destination determination unit 2 selects the link destination of the line with <! {JOKEN = 1}>, and the HTML processing unit 4 selects <SOMELINK> from </ S
<! @ JOKEN ”described between <OMELLINK>
= 1. Delete all lines except those with >>. If the description of the condition file 7 is JOKEN = 0, the link destination determination unit 2 selects the link destination of the line having <! {JOKEN = 0}>, and the HTML processing unit 4 selects <SOMELINE>.
KS> to </ SOMELINK><!
Delete all lines except those with {JOKEN = 0}>. FIG. 3 shows the contents of the file processed by the HTML processing unit 4 in this manner. At this stage, the newly acquired HTM
The L file 6 is a conventional HTML file. Then, the processed HTML file is transferred to the HTML interpreting unit 3 and displayed on the display 12 through the output unit 9 after shaping. FIG. 4 is a flowchart of the above operation.

Next, a specific second embodiment will be described.

When a link object of an HTML file already displayed on the display 12 is designated by using the mouse 11, the link destination set in the link object is input to the HTML interpreting unit 3 via the input unit 8.
The new HTML file 6 is read into the file reading unit 5 from the link destination set in the link object, and is passed to the HTML interpreting unit 3. FIG. 5 shows the contents of the HTML file 6 read at this time.

In the HTML interpreting section 3, the HTML file 6
A variable sandwiched between $$ is searched from the inside, and if there is a variable, the link destination determination unit 2 is started. The link destination determination unit 2 reads the file 13 in which the link destinations of the files referred to so far are recorded in chronological order, selects a link destination that matches the variable, and the HTML processing unit 4 uses the variable $$ back3 $$ Is replaced with the description of the selected link destination. FIG. 6 shows the contents of the file processed by the HTML processing unit 4 in this manner. At this stage, the HTML file 6 is a conventional HTML file. Then, convert the processed HTML file to HTML
It is passed to the L interpreting unit 3 and displayed on the display 12 through the output unit 9 after shaping. FIG. 7 is a flowchart of the above operation.

[0016]

As described above, the method and system for controlling the L link destination of the HTML file browser according to the present invention can set a plurality of link destinations in the link object in the HTML file and select the link destination according to the conditions. There is an effect that an appropriate link to a file can be selected depending on the setting of conditions.
