problem with attribute key on options name

if the $key is empty, there will be a problem with the xml parsing.

i think the correction should be:

if (empty($key) || $value === false) {

I'm not sure how to replicate this; are you saying that some sites would have option names that are an empty string?

[proseLA]

that's what is seems like to me. perhaps i screwed around with my data, and it's not something one would see "normally".

Thanks for the update; will get that corrected in a bit.
