How can I make a product parser with shopify and convert to xml file?

Question

PHP

Greetings, There is an online store on Shopife, you need to implement a parser, it should work according to the principle,
you entered a link to a product, it gives you an xml file of this product that you can download!
There is not so much information that you need to extract, price, description, sizes, colors, model, photo, and that's all!
The question is whether there are ready-made scripts or how can such a simple parser be implemented?
