How can I generate XML?

Question

I need to generate a XML document, using specific data from a spreadsheet.

I'm using GoogleScript, but I don't see any libraries to help me generate XML. (The standard XML Service only parses XML)

Am I forced to do this by-hand or am I missing something?

Can you recommend any libraries or Javascript functions that might assist in generating XML?

Thanks

Answer 1

You can build XML documents using HtmlService templates. You can also create documents with the Xml service by starting with an empty document (Xml.parse('') or something similar) and then manipulating it with Xml.element() and the like, but I'd suspect that the first idea is much easier.

Recently I found an ability to generate XML using a XML class (not Xml) which exists in GAS. An example is following

function makeXML() {
  var xml = new XML('<a/>');
  xml['@attrib1'] = 'atribValue';
  xml.data = 'dataValue';
  xml.data.sub_data = 'subDataValue';
  return xml.toString();
}

function doGet(e) {
  var app = UiApp.createApplication();
  app.add(app.createLabel(makeXML()));
  return app;
}

The output for this script is <a attrib1="atribValue"> <data> dataValue <sub_data>subDataValue</sub_data> </data> </a>
