js创建xml

// 创建一个新的XML文档
var xmlDoc = document.implementation.createDocument("", "root", null);

// 创建元素节点
var childNode = xmlDoc.createElement("child");
childNode.textContent = "This is a child node";

// 将子节点添加到根节点
xmlDoc.documentElement.appendChild(childNode);

// 将XML文档转换为字符串
var serializer = new XMLSerializer();
var xmlString = serializer.serializeToString(xmlDoc);
console.log(xmlString);

var xmlString = '<?xml version="1.0" encoding="UTF-8"?>' +
               '<root>' +
                   '<child>This is a child node</child>' +
               '</root>';
console.log(xmlString);

// 需要先引入xmlbuilder库
var builder = require('xmlbuilder');

// 创建XML结构
var root = builder.create('root')
                 .ele('child', {attr: {id: 1}})
                 .txt('This is a child node');

// 将XML结构转换为字符串
var xmlString = root.end({ pretty: true});
console.log(xmlString);

var xmlDoc = document.implementation.createDocument("", "root", null);
var childNode = xmlDoc.createElement("child");
childNode.textContent = "This is a <test> & example.";
xmlDoc.documentElement.appendChild(childNode);

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

<?xml version="1.0" encoding="UTF-8"?>
<root><child>This is a &lt;test&gt; &amp; example.</child></root>
