powerschool webscraper?

[David Rysdam]

The Milford school district uses this "PowerSchool" web thing so parents
can check on kids' grades (middle school and up). It's pretty useful,
for those teachers that update at a reasonable frequency.

However, there's no change detection. I guess I have to have memorized
all the grades, outstanding assignments, etc for each child so I can see
what's different when I check the next time. "Huh...it's 90% now. Was it
91% yesterday? Maybe I should click through and see if he flunked
something."

I figured I'd do a simple little script that would download the page and
just do a diff. Not so fast--it's hidden behind javascript.

I know this would be trivial for someone who has done this. Heck, it
would probably be trivial for me if I didn't have 100 other projects
going and I had time to learn the tools (looks like "htmlunit" in this
case). However, it suddenly occurred to me that someone may have
*already* done this, maybe even for Milford's particular installation.

So...have you?
