How to add first two lines and download the file in xml format?

Answer 1

Simply add attribute on resources and insert <?xml> string at the start.

function json2xml(json) {
  var a = json;
  var c = document.createElement("resources");
  var t = function (v) {
    return {}.toString.call(v).split(' ')[1].slice(0, -1).toLowerCase();
  };
  var f = function (f, c, a, s) {
    c.setAttribute("tools", "http://schemas.android.com/tools");
    c.setAttribute("tools:ignore", "MissingTranslation");

    if (t(a) != "array" && t(a) != "object") {
      if (t(a) != "null") {
        c.appendChild(document.createTextNode(a));
      }
    } else {
      for (var k in a) {
        var v = a[k];
        if (k == "ki" && t(a) == "object") {
          c.setAttribute("__pi", v);
        } else {
          if (t(v) == "object") {
            var ch = c.appendChild(document.createElementNS(null, s ? "bh" : "string"));
            f(f, ch, v);
          } else if (t(v) == "array") {
            var ch = c.appendChild(document.createElementNS(null, s ? "ni" : "string"));
            f(f, ch, v, true);
          } else {
            var va = document.createElementNS(null, s ? "ki" : "string");
            if (t(v) != "null") {
              va.appendChild(document.createTextNode(v));
            }
            var ch = c.appendChild(va);
            ch.setAttribute("name", k);
          }
        }
      }
    }
  };
  f(f, c, a, t(a) == "array");
  var xml = '<?xml version="1.0" encoding="utf-8"?>' + c.outerHTML;
  console.log(xml);
  return xml;
}
