this thread was entered a few years ago with no answer to it. I am having the same issues happen and would like to either eliminate the "XML parsing error" or have it not display as the older thread had asked for also.

----------------------------------
I have one item that I am giving free shipping on. when you go to the check out page to choose the shipping method, the canada post module box reads:

XML parsing error.
If you prefer to use Canada Post as your shipping method, please contact the Store Owner via Email.
The free shipping method also shows up as planned.

I just want to get rid of the canada post shipping option when this item is selected for checkout by it self.. is this possible?
-----------------------------------

Any help would on how to do this would be greatly appreciated
