okay, let's dive into parsing xml to json using node.js. this tutorial, part i, will focus on the fundamentals: setting up your environment, choosing a suitable library, understanding the basic xml to json conversion process, and handling simple xml structures. we'll build a foundational understanding before moving on to more complex scenarios in later parts.

**part i: getting started with xml to json parsing in node.js**

**1. prerequisites:**

* **node.js and npm (node package manager):** ensure you have node.js installed on your system. npm usually comes bundled with node.js. you can download the latest version from the official node.js website ([https://nodejs.org/](https://nodejs.org/)).
