Is there a way to specify how empty tags are formatted when xml is converted to JSON?

[colin-luke]

I have a situation where the XML I want to convert looks something like this:

<root>
    <obl>
        <obj>
            <elem1>A</elem1>
            <elem2 />
         </obj>
         <obj>
             <elem1>B</elem1>
             <elem2>A</elem2>
          </obj>
    </obj>
</root>

When I call const obj = convert(xml, {format:"object"}) the JSON is generated like this:

{
    "root": {
        "obj": {
            "obj": [
                {
                    "elem1": "A",
                    "elem2": {}
                },
                {
                    "elem1": "B",
                    "elem2": "A"
                } 
            ]
        }
    }
}

Is there a way to configure the convert function such that the empty element (the elem2 element in the first object of the array) produces an empty string or null instead of an empty object? What I'd like is something like this:

{
    "root": {
        "obj": {
            "obj": [
                {
                    "elem1": "A",
                    "elem2": null
                },
                {
                    "elem1": "B",
                    "elem2": "A"
                } 
            ]
        }
    }
}
