Is there a reason you're not using XMLBuilder? https://github.com/oozcitak/xmlbuilder-js/

为什么不使用XMLBuilder?https://github.com/oozcitak/xmlbuilder-js/

XMLBuilder seems much better suited for what you're wanting to do, and is much, much more popular (ex: 4 million downloads in the last month). xml2js is better suited for reading in Javascript, but XMLBuilder is definitely what you'd want to use.

XMLBuilder似乎更适合您想要做的事情，而且更受欢迎(例如:上个月的下载量为400万次)。xml2js更适合在Javascript中读取，但XMLBuilder肯定是您希望使用的。

And if I'm reading correctly... xml2js is just building on XMLBuilder anyway.

如果我没看错的话……xml2js只是构建在XMLBuilder之上。

var builder = require('xmlbuilder'),
    xml = builder.create('root'),
    products = xml.ele('products'),
    product;

_.each(list, function(element) {
    product = products.ele('product');
    product.att('id', element.id);
    product.ele('name', null, element.name);
    product.ele('price', null, element.price);
});

xml = xml.end();
fs.writeFile('pacotes.xml', xml, (err) => {
    if (err) throw (err);
});
