Looking for a JSON2XML converter and back in Javascript (xml2js)

Question

I try to convert an JSON Object into XML and back again in Javascript. The best so far I found is xml2js. But even this doesn't convert correct:

A simple json like this: {name:"name1", list:["entry1","entry2"]}

converts to xml like this:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <root>
      <name>name1</name>
      <list>entry1</list>
      <list>entry2</list>
    </root>

going back to JSON I get this:

'{"root":{"name":["name1"],"list":["entry1","entry2"]}}'

The Problem is, that the name property is converted into a list []

My Code:

var xml2js = require('xml2js');
var testObject = {name:"name1", list:["entry1","entry2"]}

var builder = new xml2js.Builder();
var xmlOutput = builder.buildObject(testObject);
console.debug(xmlOutput);

var parseString = require('xml2js').parseString;
parseString(xmlOutput, function (err: any, result: any) {
    var json = JSON.stringify(result)
    console.dir(json);
});

Does anyone know whats wrong or suggest another converter to do this?
