It seems getRow() and getCol() always return 0 for html, body, and head tags.
I suspect it is because these nodes are created automatically and htmlcleaner doesn't copy the numbers over when the actual element is discovered.
I tested this both with 2.4 and with SVN revision 212.
Thanks for the report - what was the behaviour under 2.2.1?
As far as I can tell, getRow and getCol are not defined in 2.2.1.
