Converting XML to JSON in Liquid Template Language: A Simple Guide

If you're a developer working with Liquid template language, you might find yourself needing to convert XML data into a JSON format. This task may seem simple, but it often poses challenges, especially when dealing with nested arrays. This post outlines a common problem faced during such conversions and provides a reliable solution to help streamline the process.

The Problem

Consider the following XML structure representing a ticket:

However, during the conversion process using Liquid templates, many developers encounter issues where the arrays do not populate correctly, resulting in empty strings for the cc-email and fwd-email fields. Let's take a look at how to tackle this problem effectively.

Understanding the Solution

Initial Attempts

Initially, a developer attempted to use the following Liquid template code:

While it's a great starting point, this method resulted in empty outputs for the email fields.

A Working Solution

After some trial and error, a more effective solution was found using string appending. Here’s the revised code to achieve the desired result:

Breakdown of the Solution

Initialization: Start by initializing an empty string cc-email-list to store the concatenated emails.

Looping Through Items: Use a for loop to iterate through each item in the cc-emails array.

Appending Emails: Within the loop:

Append each email to cc-email-list.

Check if the current item is the last in the loop. If it's not, also append a comma to separate multiple email addresses.

Final Output: Use the populated cc-email-list variable to create the cc-email field in the final JSON output.

Final JSON Output

With the provided solution, the output will now accurately reflect the desired JSON format:
