I have got a version of the Stack Overflow dump data dated September 2011. In the votes file the lines are like this format:
<row Id="1" PostId="4" VoteTypeId="2" CreationDate="2010-09-13" />
id is the serial number,
postid is the post that received the vote, and
VoteTypeId is the vote type (in this case it is UpMod).
In this format I can not know what user voted on the post, is it normal? Or I have just got a bad dump; if so, where can I download a better version?
