If you're passing parameters with a question mark like you have shown then that is a GET, and not a POST.
In general terms you're going to want to write a script to output all the urls to a text file, which should be a simple for/while loop. You can then use wget to download all of these (wget -i links.txt). And finally you'll want to write a script with a regex to pull the relevant data. That is of course unless you can find software to do it all for you.
To get the list of urls, if they are all GET requests with incremental numbers passed, visit the first one and then use the following javascript bookmarklet:

So now you're just left with having to write a script to find the text which differs between each file.
