Abstract

Embodiments of the present invention use a new extension to the HTML language to support remotely specified named anchors. A remotely specified named anchor, when embedded within a source document, instructs a browser program to access a portion of a destination document indicated in the remotely specified named anchor. When the browser program reads a remotely specified named anchor such as

<a href=http://foo.com/bar.html/SCROLL="Some Text">

from the source document, the browser program performs the following steps: 1) the browser retrieves the destination file "bar.html" from the server "foo.com", 2) the browser searches the file bar.html for "Some Text", and 3) if the browser finds the character swing being searched for, then the browser displays the file bar.html, scrolled to the line containing the first character of the character string being searched for.

Claims

1. A method executed in a network computer system for facilitating access to a specified portion of data stored at a remote location, the method comprising the steps of:

retrieving a source document, the source document including hypertext links to other data on the network;

displaying the source document;

receiving input entered on the source document;

determining whether the input comprises selection of a remotely specified named anchor;

when the input comprises selection of a remotely specified named anchor, retrieving data indicated in the remotely specified named anchor and displaying a portion of the data specified in the remotely specified named anchor, wherein the specified portion of the data does not have a position marker associated with it.

2. The method of claim 1 wherein the step of determining further comprises the step of:

examining the remotely specified named anchor to determine whether it contains an attribute indicating that a specified portion of the retrieved data should be displayed.

3. The method of claim 2 wherein the attribute is a SCROLL attribute.

4. The method of claim 1 wherein the step of displaying the portion of the data specified in the remotely specified named anchor further comprises the step of:

examining the remotely specified named anchor to determine a character string to search for.

5. The method of claim 4 further comprising the steps of:

searching the retrieved data for the character string; and

displaying the portion of the data containing the character string.

6. A network computer system for facilitating access to a specified portion of data stored at a remote location, the system comprising:

a mechanism configured to retrieve a source document, the source document including hypertext links to other data on the network;

a mechanism configured to display the source document;

a mechanism configured to receive input entered on the source document;

a mechanism configured to determine whether the input comprises selection of a remotely specified named anchor;

a mechanism configured to, when the input comprises selection of a remotely specified named anchor, retrieve data indicated in the remotely specified named anchor and display a portion of the data specified in the remotely specified named anchor, wherein the specified portion of the data does not have a position marker associated with it.

7. The system of claim 6 wherein the mechanism configured to determine further comprises:

a mechanism configured to examine the remotely specified named anchor to determine whether it contains an attribute indicating that a specified portion of the retrieved data should be displayed.

8. The system of claim 7 wherein the attribute is a SCROLL attribute.

9. The system of claim 6 wherein the mechanism configured to display the portion of the data specified in the remotely specified named anchor further comprises:

a mechanism configured to examine the remotely specified named anchor to determine a character string to search for.

10. The system of claim 9 further comprising:

a mechanism configured to search the retrieved data for the character string; and

a mechanism configured to display the portion of the data containing the character string.

11. A computer program product for facilitating access to a specified portion of data stored at a remote location, the computer program product comprising:

code that retrieves a source document, the source document including hypertext links to other data on the network;

code that displays the source document;

code that receives input entered on the source document;

code that determines whether the input comprises selection of a remotely specified named anchor;

code that, when the input comprises selection of a remotely specified named anchor, retrieves data indicated in the remotely specified named anchor and displays a portion of the data specified in the remotely specified named anchor, wherein the specified portion of the data does not have a position marker associated with it,

wherein the code resides on a tangible medium.

12. The computer program product of claim 11 wherein the code that determines further comprises:

code that examines the remotely specified named anchor to determine whether it contains an attribute indicating that a specified portion of the retrieved data should be displayed.

13. The computer program product of claim 12 wherein the attribute is a SCROLL attribute.

14. The computer program product of claim 11 wherein the code that displays the portion of the data specified in the remotely specified named anchor further comprises:

code that examines the remotely specified named anchor to determine a character string to search for.

15. The computer program product of claim 14 further comprising:

code that searches the retrieved data for the character string; and

code that displays the portion of the data containing the character string.
