如何在JavaScript中将数组转换为XML

var xmlDoc = document.implementation.createDocument(null, null, null);

var rootElement = xmlDoc.createElement("root");
xmlDoc.appendChild(rootElement);

var array = [1, 2, 3];
for (var i = 0; i < array.length; i++) {
  var element = xmlDoc.createElement("item");
  element.textContent = array[i];
  rootElement.appendChild(element);
}

var xmlString = new XMLSerializer().serializeToString(xmlDoc);

var xmlDoc = document.implementation.createDocument(null, null, null);
var rootElement = xmlDoc.createElement("root");
xmlDoc.appendChild(rootElement);

var array = [1, 2, 3];
for (var i = 0; i < array.length; i++) {
  var element = xmlDoc.createElement("item");
  element.textContent = array[i];
  rootElement.appendChild(element);
}

var xmlString = new XMLSerializer().serializeToString(xmlDoc);
console.log(xmlString);
