如何将JavaScript对象转换为XML

function convertToXML(obj) {
  var xml = document.createElement("xml");

  for (var key in obj) {
    if (obj.hasOwnProperty(key)) {
      var element = document.createElement(key);
      element.appendChild(document.createTextNode(obj[key]));
      xml.appendChild(element);
    }
  }

  return new XMLSerializer().serializeToString(xml);
}

// 示例对象
var obj = {
  name: "John",
  age: 30,
  city: "New York"
};

// 转换为XML
var xmlString = convertToXML(obj);
console.log(xmlString);

<xml>
  <name>John</name>
  <age>30</age>
  <city>New York</city>
</xml>
