Twitter data-url and a jquery generated list

Hello Everyone,

I need a bit of help on this one. I am using this bit of jquery (https://github.com/sdepold/jquery-rss) to generate an rss list. Works great - no problems; however, I would like to place a "tweet button" next to each generated list item (each item in the rss). I want that tweet button to pull the url of the jquery generated link into the tweet message. Twitter (https://dev.twitter.com/docs/tweet-button) has a function build into their tweet button (data-url) that will allow you to specify a specific link (instead of the default page link); however, how can I tell the data-url that the link I want is X url that is generated list? Because this is an rss feed, the links are constantly changing.

In other words, I will use the jquery-rss code to create an unordered list of latest four posts on a blog. EACH list item contains a javascript created title, url, and a snippet of the post body. How can I get the url out of that jquery generated list item and pull it into twitter's data-url class? Any ideas? For the code, simply use the example code provided by github and twitter developers page.

Thanks
