Hi Kevin,
I'm terribly sorry for bothering you with this old post, but I have the same problem and by following the link that you gave I can see that you can download the csv files with the drug name and the protein that correspond but I was wondering if you can have an information about the action (inhibitor, antagonist, etc.) This information exists only in the full xml file (as far as I understand) but not in the csv.
Thank you very much,
Vasilis
