Generating XML on the Fly with SuiteScript 2.0 in NetSuite

If you are working with NetSuite and need to generate XML using SuiteScript 2.0 on the server-side, you might have run into some challenges. This post addresses a common scenario: creating XML dynamically rather than reading from a static file. Below, we will walk you through the process step-by-step, using the N/xml module in SuiteScript 2.0.

The Problem Statement

You are tasked with generating XML as a string within a Suitelet script using SuiteScript 2.0. Unlike client-side scripts where you can manipulatively build strings, server-side scripting involves utilizing the N/xml module, specifically its Document, Element, and Node functionalities. For illustration, you seek to produce the following XML structure:

The end goal is to return this XML format as a string, something like:

However, you encountered an error when trying to append child nodes: "HierarchyRequestError: Failed to execute 'appendChild' on 'Node': Only one element on document allowed." This error suggests an issue with how you are manipulating the XML document's structure.

Solution Overview

To effectively generate XML, we will require the N/xml module. Here is a streamlined approach to achieving our goal:

Create an XML Document: Use the Parser to build an XML structure.

Add Child Elements: Dynamically append elements like book, title, and author to our XML document.

Convert to String: Finally, convert the document to a string format that can be returned.

Step-by-Step Implementation

Step 1: Utilize the N/xml Module

First, include the N/xml module in your SuiteScript. This module will grant you the methods needed to create and manipulate XML documents.

Conclusion

Generating XML using SuiteScript 2.0 in NetSuite can initially seem daunting, especially when working with the server side. However, by leveraging the N/xml module, you can create XML documents programmatically with ease. Follow the outlined steps, and soon you will be able to generate dynamic XML structures tailored to your needs.

With this guide, you’re now prepared to tackle XML generation in your Suitelet scripts effectively. Happy coding!
