The page I pointed to does have tools that are stand-alone, install it on your own server solutions, as well as ones that use a third party. Here’s the link: http://www.rssgov.com/rssparsers.html

Since anything that does this will require some scripting, all of the programs that you would install on your own site will work (or not) depending on whether your server already has the “libraries” that the program needs to work (a PHP script would need the PHP library, for example). Third party services consolidate this, because they control the server the program is on, and so the maintainer only has to make sure his or her own server has both the program and the libraries the program requires).

So if you use one of the standalone tools, you have two approaches you could use:
1. Install it and see if it works. If it works, you have the right libraries
2. Do a little research to find out how you can figure out what libraries are on your server, either by asking the maintainer, or using some tool that “scans” the server and says, okay, this server has PHP, Perl, Python installed. I don’t know much about the latter, I’ve been teaching myself PHP, and I know after I did the first exercise there was a thing on checking what version of PHP you had…

Sorry you didn’t get any answers the first time. I’m sure Jenny Levine has a way to do this because she’s been promoting it in her talks. If you search on convert rss to html or rss parsers you’ll get a few. Here’s a link to one: http://www.geckotribe.com/rss/carp/ but I can’t say how well it works. Here’s another one: http://jade.mcli.dist.maricopa.edu/feed/
