Here is one possible solution:

var inputString = "OMDB DB464 IVURO KUSEN LALDO GIDIL IMLOT 2500N/05700E KATUS PEDEX KINOX EGPIC EGRON LAKIV OPKC";
var waypoints = inputString.split(" ");

var xml = '<?xml version="1.0" encoding="utf-8"?>\n' +
    '<flight-plan xmlns="http://www8.garmin.com/xmlschemas/FlightPlan/v1">\n' +
    '  <created>' + new Date().toISOString() + '</created>\n' +
    '  <waypoint-table>\n';

for (var i = 0; i < waypoints.length; i++) {
  var waypoint = waypoints[i];
  var countryCode = "XX";
  if (waypoint.endsWith("N")) {
    countryCode = "OO";
  } else if (waypoint.endsWith("E")) {
    countryCode = "OI";
  } else if (waypoint.endsWith("C")) {
    countryCode = "OP";
  }

  var identifier = waypoint.replace(/[0-9]/g, '').replace("/",'');
  var lat = parseFloat(waypoint.substring(waypoint.indexOf("N") - 4, waypoint.indexOf("N")))/100;
  var lon = parseFloat(waypoint.substring(waypoint.indexOf("E") - 4, waypoint.indexOf("E")))/100;
  var type = "INT";
  if (i === 0) {
    type = "AIRPORT";
    countryCode = "OM";
  }
  xml += '    <waypoint>\n' +
      '      <identifier>' + identifier + '</identifier>\n' +
      '      <type>' + type + '</type>\n' +
      '      <country-code>' + countryCode + '</country-code>\n' +
      '      <lat>' + lat + '</lat>\n' +
      '      <lon>' + lon + '</lon>\n' +
      '      <comment />\n' +
      '    </waypoint>\n';
}

xml += '  </waypoint-table>\n' +
    '</flight-plan>';
console.log(xml);

Please note that this is an example and it's not guaranteed to work for all cases and it does not handle the case where the input string is not well formatted.
