var builder = require('xmlbuilder');
var doc = builder.create('root');

doc.ele('xmlbuilder')
    .att('for', 'node-js')
    .ele('repo')
      .att('type', 'git')
      .txt('git://github.com/oozcitak/xmlbuilder-js.git') 
    .up()
  .up()
  .ele('test')
    .txt('complete');

console.log(doc.toString({ pretty: true }));

Thanks Shard. Just more E6 convention: `

const getFile = dir => new Promise((resolve, reject) => {
  fs.readFile(dir, 'utf8', (err, data) =>
    (err ? reject(err) : resolve(data)));
});

const parseXml = xml => new Promise((resolve, reject) => {
  require('xml2js').parseString(xml, (err, result) =>
    (err ? reject(err) : resolve(result)));
});

const xmlFileToObject = dir => getFile(dir)
  .then(xml => parseXml(xml))
  .then(result => console.log(result))
  .catch(e => console.error(e));

`

Bumped into this post on google, I was looking for something slightly different, but here, this code of mine should solve this problem for anyone else who comes across this post.

function xmlFileToObject(path) {
    return new Promise((resolve,reject) => {
        getFile(path).then(xml => {
            parseXml(xml).then(result => {
                resolve(result);
            });
        });
    });
}
function getFile(path) {
    return new Promise((resolve, reject) => {
        fs.readFile(path, 'utf8', function (err,data) {
            if (err) console.error(err);
            resolve(data);
        });
    });
}
function parseXml(xml) {
    return new Promise((resolve,reject) => {
        var parseString = require('xml2js').parseString;
        parseString(xml, function (err, result) {
            resolve(result);
        });
    });
}
