There's no need to use ngrok with any other framework or tool. ngrok is a way to create a public URL that tunnels traffic down to an application server running on localhost. The page you link to makes no mention of XAMPP.

You can serve static XML over ngrok, you just need a web server to serve it on localhost. You can also serve the XML from something like an Express application, or whatever you want.

For deploying to production, you don't even want to use ngrok, as that is a tool for tunnelling to your localhost. You can either host your XML anywhere staticly online, or run a web server with an application to generate it or even use something like Twilio Functions to run Node.js code to generate your XML.

It's mostly up to you how you produce your XML, ngrok is just one tool that helps you test your webhook applications locally.
