x2js是一个 实现 XML 与 JavaScript 对象之间相互转换的工具库。转换并不一定是无损的，但十分便利。

x2js

XML 转换为 JavaScript 对象

    var x2js = new X2JS();    var document = x2js.xml2js("<foo><a>1</a></foo>");    console.log(document.foo); // 输出：Object {a: "1"}

JavaScript 对象转换为 XML

    var xml = x2js.js2xml({foo: {a: 1}});    console.log(xml); // 输出：<foo><a>1</a></foo>

x2js 使用

    var x2js2 = new X2JS();    var xml = `<?xml version="1.0" encoding="UTF-8" ?><business><company>Code Blog</company><owner>Nic Raboy</owner><employee><firstname>Nic</firstname><lastname>Raboy</lastname></employee><employee><firstname>Maria</firstname><lastname>Campos</lastname></employee></business>`;

    var document = x2js2.xml2js(xml);     
    console.log(document.business.company); // 输出：Code Blog
    console.log(document.business.owner); // 输出：Nic Raboy
    console.log(document.business.employee[0].firstname); // 输出：Nic
    console.log(document.business.employee[0].lastname); // 输出：Raboy
