Make an RSS Feed with Google Apps Script

Published in: Google Apps Script - RSS

ThinkAmI uses the XMLService of Google Apps Script to create a valid RSS feed that is served to the browser using ContentService with the MIME type set as RSS. Should be handy for creating RSS feeds for services like the Google Search Scraper that do not natively offer feeds.

function doGet() {

    var rss = makeRss();

    rss.setTitle('RSS 2.0 Feed with Google Apps Script');
    rss.setDescription('RSS 2.0 Feed');

    for (var i = 1; i < 3; i++) {
            title: 'TITLE:' + i,
            link: '' + i,
            description: 'DESCRIPTION: ' + i,
            pubDate: new Date()

    return ContentService.createTextOutput(rss.toString())

var makeRss = function () {
    var channel = XmlService.createElement('channel');
    var root = XmlService.createElement('rss')
        .setAttribute('version', '2.0')

    var title = '';

            var document = XmlService.createDocument(root);
