doing simple data analysis on list archives

The Museum Computer Network (http://mcn.edu) is having their 50th 
anniversary this year and I'm doing a volunteer project where I'm 
looking at the history of computery museum jobs. Fortunately, a couple 
years ago I put every mcn-l posting since 1996 up on The Mail Archive 
and there are ~1000 job postings in there. (Other people get to look at 
old print publications for the earlier history).

It's easy enough on mail-archive to search for "job" or "position" and 
get the results. The expand button gets me the content of each message 
right on the search results page. Hence,

https://www.mail-archive.com/search?l=mcn-l%40mcn.edu&q=%28%2Bjob+OR+%2Bposition%29&f=1

And the HTML of that page is nicely structured. I'd love to get them 
from there into a spreadsheet and figure out things like "most job 
postings go out at the end of the month" or "we stopped saying 
'webmaster' in 2001" or other kinds of data-informed insights. Has 
anybody tried something like this before?

I guess what I'm asking, is there an easy path from mail-archive.com 
search results into a spreadsheet (I guess mySQL or postgres would be OK 
too) or some other kind of analysis tool?

Thanks!
Matt
