Working on Printer Class 4015

For the class of printer P4015, we need to use the DOM to pull out
relavent info. The info we want is contained at 2 urls. I wrote a
function that takes a url as an argument and returns an array of all
divs at the given web page.

I need to figure out how to use this to extract the proper information.
I also need to find out if the same code will extract the right same
info on other P4015 printer's web interface.
