It did precisely what your sample gave said to do...

Well, that makes no sense from the supposed output below where there's a 0 0 given for element 1  there's no 0 0 in the coord array for a node 4.
So, I don't think you've got what you want down precisely yet...
...

Try again, that doesn't seem to work to me.
Where, again, do you think the '0 0' come from for the first entry, now?
