Array with null elements crashes program

[JonathanWilbur]

xml({ foo: null }) works fine, but xml({ bar: [ null, null ] }) causes the program to crash. I know it seems like an edge case, but I am converting a JSON document from a database query and some documents contain arrays with null elements.

Here is the stack trace:

events.js:160 throw er; // Unhandled 'error' event ^ TypeError: Cannot convert undefined or null to object at /x/node_modules/xml/lib/xml.js:185:44 at Array.forEach (native) at resolve (/x/node_modules/xml/lib/xml.js:183:24) at add (/x/node_modules/xml/lib/xml.js:47:24) at xml (/x/node_modules/xml/lib/xml.js:89:9) at [REDACTED] at Query.

i would assume this is an intended feature.
