Finding the Wi-Fi username in a xml file?

So i need to join a wpa2 enterprise network which i have my laptop connected to but i need my phone to be connected too, i have all the Wi-Fi certificates required installed on my iphone, but the only thing i can't install is the wireless profile for the Wi-Fi (the xml file) and when i try and join through my phone it keeps asking for a username? Is it possible to find this username in the xml somewhere?

I doubt if any of that would be visible.
