scripting help

[killabath]

I've been working on trying to get URL.

for example, if I'm at "www,website,com/part=example&part"]
I want to be able to take the URl and assign a variable to it
but not JUST that, I also need help cutting out a certain section

I want to cut out the "example" from that, and use only that part as the variable, the example will constantly be changing, but there will ALWAYS be a "=" before it, and occasionally a "&" behind it

thanks in advance for any help with this, it's really appreciated
