The printf statement in the OP has one argument which includes interpolated strings from some arbitrary XML. It's quite possible that those contain unescaped % symbols. With certain input I'm sure such warnings could be generated by catfish1116's code.

However since catfish1116 still hasn't deigned to provide us with the input data, despite numerous requests in the other thread, it's all just guesswork.
