Encode thread in RSS by a URL grabber

[Desi-Home]

I'm not sure if this is possible or not.. I know it's possible to encode a full thread contents using the following code.

{feed:content:encoded}

but i want to encode a thread by it's URL.. like if there's such thing to encode another website's contents by a link so incase they make changes to the thread it' should automatically make changes at my forum too since the thread will be encoded by URL.. please help me.. something like following

{feed:content:http://mydesi.tv/post blah blah..}
