Yes. I've lost count how many times I've implemented Google Tag Manager or Google's product feed on the ecommerce sites I build and maintain. Sometimes its a standard install (I should get around to building a collection of libraries for stuff like this). Othertimes it's a totally customized bespoke setup that tracks things down to individual clicks on every page (a good flag that the client is on its last legs). Similarly, for those sites, I have a collection of Python scripts that translate between CSV and the standardized XML imports that the ecommerce platform uses (SFCC). I almost certainly have to modify it a bit for different heading names, but it works pretty well. When I use Java and need to search through XML, I built a class that searches for a specified child element, because the NodeList class isn't iterable (can't be used in a for each).
