如何使用Google Apps脚本的XmlService设置XML元素的名称空间？

Question

I'm programmatically creating XML documents using Google Apps Script's XmlService . However, I can't figure out how to add a namespace to an element. How do I use the XmlService API to add a namespace to an individual XML element?

You can add the namespace to an element when you create the element. See XmlService.createElement(String, Namespace) . However, Google Apps Script will raise an error if you attempt to pass a string literal for the second argument. What you need to do is call XmlService.getNamespace(prefix, uri) method to create a Namespace object. You can then pass that Namespace object as the second arg.

// Create a namespace object.
ns = XmlService.getNamespace("xsi", 
    "http://www.w3.org/2001/XMLSchema-instance");

// Create an element.
var el = XmlService.createElement('devdef');

// Set the namespace of the element. 
el.setNamespace(ns);
