Possible to get open graph data for comments box?

Question

Is it possible to get a list of comments, or at least a count of the number of comments that have been left on a website with the Facebook comments widget?

The widget I am using is placed inside an iFrame Facebook application.

Here is the XFBML which is being parsed by the Facebook Javascript API:

<fb:comments xid="fbtest"></fb:comments>

Would the xid parameter have anything to do with it? As far as I can tell, there are no other possible parameters. How would one query the open graph url (http://graph.facebook.com/QUERY) to access this object?

Answer 1

You can do this with FQL:

select post_id, text from comment where xid="fbtest"

see comment table
