Cannot round-trip encoding/decoding

[adamvoss]

Given the following object as x:

[
    {
        "id": 2,
        "name": "An ice sculpture",
        "price": 12.5,
        "tags": [
            "cold",
            "ice"
        ],
        "dimensions": {
            "length": 7,
            "width": 12,
            "height": 9.5
        },
        "warehouseLocation": {
            "latitude": -78.75,
            "longitude": 20.4
        }
    },
    {
        "id": 3,
        "name": "A blue mouse",
        "price": 25.5,
        "dimensions": {
            "length": 3.1,
            "width": 1,
            "height": 1
        },
        "warehouseLocation": {
            "latitude": 54.4,
            "longitude": -32.7
        }
    }
]

The following fails (prints an error):

builder = new xml2js.Builder()
xml2js.parseString(builder.buildObject(x), function(err, res) { console.log(err) })

with the following error:

Using 0.4.17 from npm

The main problem is that x is an array, not an object. The input to buildObject should be an object with one named property whose value is not an array. Otherwise, the results are more or less undefined.

@adamvoss, if you still have this issue, please let us know what you want to do (e.g. by posting a short XML sample etc.) and we can help you find a way.
