Converting JSON with Repeated Tags to XML: A Guide using xmlBuilder in Node.js

In the world of data structuring, developers often face the challenge of transforming data formats in a way that is both efficient and maintainable. One common issue that arises is converting JSON objects into XML, especially when dealing with repeated tags. If you have ever found yourself in such a situation, you're not alone!

In this guide, we will explore how to generate XML with repeated tags using the xmlBuilder library in Node.js, while ensuring that you have a clear understanding of each step involved.

The Problem

You've prepared a JSON structure that you wish to convert to XML, but you're facing a hurdle with repeated tags. For example, you want to convert the following JSON:

into this XML format:

The difficulty lies in representing the repeated tag <C>, which is meant to have multiple values. Let’s walk through how to properly structure your JSON and use xmlBuilder to achieve the desired XML output.

The Solution

To address this issue, we need to make a slight modification to the way we define the JSON structure. Instead of treating each tag as a single value (with C being unclear), we should define C as an array. Here's how you can structure the JSON correctly:

Breaking Down the XML Conversion

Using the xmlBuilder Library: This library simplifies the XML creation process from JSON in Node.js. First, make sure to install it via npm:

Output

When you run the above code, it will produce the following XML structure:

This approach not only resolves the challenge of repeated tags but also gives you flexibility for any additional transformations or manipulations you might need in your XML content.

Conclusion

Transforming JSON to XML, especially when dealing with repeated tags, can be complicated, but it can be done effectively using libraries like xmlBuilder in Node.js. By converting your JSON structure properly and implementing a simple loop for repeated tags, you can achieve the desired XML output seamlessly.

With this guidance, go ahead and tackle your data structuring problems with confidence!
