const data = {
  SolarSystem: {
    Galaxy: "\"MilkyWay\"",
    Star: () => "Sun",
    Planet: [
      {
        "position": "1",
        "name": "<Mercury>",
        "distance": "58",
      },
      {
        "position": "2",
        "name": "Venus",
        "distance": "108"
      }
    ],
    Planet1: {
      "@": {
        position: "3",
        distance: "149"
      },
      name: "Earth"
    },
    Planet2: {
    "@": {
      position: "4",
      distance: 227,
    },
    "#": {
        name: {
          "#" : 'mars',
          "@": {
            "has-water": 'true'
          },
        },
        moon: [
          undefined,
          'Europa',
          'Deimos'
        ]
      }
    }
  }
}

const xml = parser.jsXml.toXmlString(data);

<?xml version="1.0"?>

Type Handling

const options = {
  typeHandler: (v) => [true, v]; 
  // return [<bool for creating tag>, <value>]
  // runs for every nested property
}

Using Options

const Options = {
  beautify: true,
  selfClosing: true,
  typeHandler: (v) => {
    if([undefined, null, ''].includes(v)) {
      return [false, v]
    }
    return [true, v]
  }
}

const data = {
  SolarSystem: {
    Galaxy: undefined,
    Star: () => null,
    Planet: 'Earth'
  }
}
const xml = parser.jsXml.toXmlString(data, Options);

<?xml version="1.0"?>
<SolarSystem>
 <Planet>Earth</Planet>
</SolarSystem>
