Technical question about the filibuster

[adamuu]

There's this page
http://senate.gov/legislative/LIS/roll_call_lists/vote_menu_111_2.htm
If I count up all the columns with Question="On the cloture motion" and Result="Rejected" will the equal the number of filibusters exercised by the 41-Republican obstructionist caucus?

I guess in a more general sense, is the an official source of all the votes blocked by the filibuster, preferably in XML format?

I have an idea for a visibility project.

1. Is voting against cloture the same as filibuster?

Sounds pretty antiseptic for something once thought of as so dramatic.

2. On Rachel Maddow last Friday there was a column graph of the filibuster tally. Where is raw data?

I froze the video. The source says http://www.ourfuture.org/ and http://www.senate.gov/
I searched http://www.ourfuture.org/ but I can't find that graph
I found roll coll votes at http://www.senate.gov/ in XML format, but I don't see how the numbers shown in the graph can be supported by the roll call votes.

I have an idea for a project, but it requires filibuster counts. Is this just something the media keeps track of on the side, or is it there official tally somewhere?
Can anyone help?
