Abstract

This document describes techniques for, and apparatuses capable of, provider-specific parsing for content retrieval. In one embodiment, a user'"'"'s computing device receives code (e.g., an executable script) from a content provider and utilizes a parsing scheme associated with the content provider to parse the code and determine an address that can be used to retrieve an instance of content. The instance of content can then be retrieved using the address and without executing the code. In some embodiments, the parsing scheme is specific to the content provider and can be updated based on a change to the code.

Claims

1. A computer-implemented method comprising:

receiving code associated with an instance of content from a content provider;

ascertaining a parsing scheme associated with the content provider;

parsing the code using the parsing scheme to determine an address for the instance of content; and

retrieving the instance of content using the address.

2. The method as recited in claim 1, wherein the code comprises one of more of an executable script, a playlist file, or markup code.

3. The method as recited in claim 1, wherein receiving the code associated with the instance of content is responsive to a request from a device for the instance of content and wherein ascertaining the parsing scheme comprises:

determining that the device that requested the instance of the content cannot execute the code; and

receiving the parsing scheme from a remote resource responsive to the determining that the device that requested the instance of content cannot execute the code.

4. The method as recited in claim 1, wherein ascertaining the parsing scheme comprises selecting the parsing scheme from a plurality of parsing schemes associated with a plurality of content providers.

5. The method as recited in claim 1, wherein ascertaining the parsing scheme comprises:

determining that the parsing scheme needs to be updated; and

receiving an updated version of the parsing scheme from a remote resource.

6. The method as recited in claim 5, wherein the determining that the parsing scheme needs to be updated is responsive to receiving an indication of one or more changes to the code associated with the instance of content.

7. The method as recited in claim 1, wherein the address comprises one or more of a uniform resource locator (URL) or a uniform resource identifier (URI) for the instance of the content.

8. The method as recited in claim 1, wherein parsing the code using the parsing scheme to determine the address for the instance of the content comprises parsing at least a portion of a website associated with the provider of the instance of the content.

9. A computer-implemented method comprising:

maintaining parsing schemes for a plurality of content providers;

determining that one of the parsing schemes needs to be updated; and

causing the one of the parsing schemes to be updated to produce an updated parsing scheme.

10. The method as recited in claim 9, wherein one or more of the parsing schemes are configured to parse code associated with one or more of the plurality of content providers to determine an address for an instance of content associated with the one or more of the content providers.

11. The method as recited in claim 9, wherein determining that the one of the parsing schemes needs to be updated is responsive to a request from a remote device for an updated parsing scheme.

12. The method as recited in claim 9, wherein determining that the one of the parsing schemes needs to be updated is responsive to receiving an indication from a remote device of a failure of the one of the parsing schemes.

13. The method as recited in claim 9, wherein determining that the one of the parsing schemes needs to be updated is responsive to an indication from one of the plurality of content providers that the one of the parsing schemes needs to be updated.

14. The method as recited in claim 9, further comprising:

determining that a remote device previously received the one of the parsing schemes; and

pushing the updated parsing scheme to the remote device.

15. One or more computer-readable media storing computer-executable instructions, the instructions comprising:

a parsing module manager configured to store a plurality of parsing modules, one or more of the parsing modules being specific to a content provider and being configured to parse code associated with the content provider to determine an address for an instance of content associated with the content provider; and

a parsing module updater configured to cause the one or more of the parsing modules to be updated.

16. The one or more computer-readable media of claim 15, wherein the code associated with the content provider comprises one or more of an executable script, a playlist file, or markup code.

17. The one or more computer-readable media of claim 15, wherein the parsing module manager is further configured to push the one or more of the parsing modules to a remote device responsive to an indication of a request from the remote device for the instance of content.

18. The one or more computer-readable media of claim 15, wherein the parsing module updater is further configured to cause the one or more of the parsing modules to be updated responsive to an indication of a change in the code associated with the content provider.

19. The one or more computer-readable media of claim 18, wherein indication of the change in the code comprises an indication of a change to a website associated with the content provider.

20. The one or more computer-readable media of claim 15, wherein the parsing module manager is further configured to maintain a list of devices that have requested at least one of the parsing modules and, responsive to the at least one of the parsing modules being updated, push an updated version of the at least one of the parsing modules to the devices.
