Node.js: How to create XML files

It looks like the xmlbuilder-js library may do this for you. If you have npm installed, you can npm install xmlbuilder.

It will let you do this (taken from their example):

var builder = require('xmlbuilder');
var doc = builder.create('root');

doc.ele('xmlbuilder')
    .att('for', 'node-js')
    .ele('repo')
      .att('type', 'git')
      .txt('git://github.com/oozcitak/xmlbuilder-js.git') 
    .up()
  .up()
  .ele('test')
    .txt('complete');

console.log(doc.toString({ pretty: true }));

which will result in:

<root>
  <xmlbuilder for="node-js">
    <repo type="git">git://github.com/oozcitak/xmlbuilder-js.git</repo>
  </xmlbuilder>
  <test>complete</test>
</root>
