I need some help with web pages and xml. I've seen the example where the web page is served from an SD card and xml files are sent to get analog data to drive a gauge or two on the web page.
I want to do the same thing but I want my web page to be served from my Mac. Not the Arduino. I don't quite understand how to interact with the Arduino via xml from a browser that has been served a page from a web server not on the Arduino.
Any ideas as to how to do this would be appreciated. It can be with other methods as I'll consider any options
