I am looking for an RSS parser with a GUI interface that will let me simply input the RSS feed and have complete control over the out put through selections before generating the output.

I need PHP, JavaScript, and HTML or iFrame output.

Something similar to http://rss-info.com/en_rssinclude-simple.html but I need to be able to host it myself.

I am not an RSS expert, and have tried Magpie and Carp, neither of which I could completely figure out or understand.

What I need:
RSS feed from my forum to be able to be displayed on various sites which have different coding capabilities. For example, one site allows posting of javascript and HTML, the other site only allows HTML in an iframe.

Why I need it:
I have a fantasy football website, Kansas City Fantasy - Home, for all the fantasy football leagues I play in. To keep it as organized as possible, I want to use the forums on my website instead of the message boards on the individual league websites. The problem it that some owners simply cannot grasp the idea of "do not use the message board on the league site." Other owners complain about messages being posted on two sites and keeping up with both of them, while many of the owners play in multiple leagues, they would rather us the forum, as would I.

What I have:
Site Type #1 - Fantasy Football League Management From MyFantasyLeague.com - Demo: Fantasy Football: Kansas City Keeper
RSS feed - KC Keeper - Latest Posts
Used to convert RSS to javascript: http://www.rss-info.com/en_rssinclude-simple.html

Using various JS methods i have re-routed all the Message Board links to the KC Fantasy forum (links titled "KCAK Forum") and I have inserted a module with the RSS feed.

Site Type #2 - ESPN.com: Fantasy Football Index - Demo: ESPN Fantasy Football 2008: AKC League Office
RSS Feed: AKC - Message Board
Used to convert RSS to iframe: http://www.rss-info.com/en_rssinclude-simple.html

Using iframe I have inserted the RSS feeds into the hompage of this league. It is not possible to deactivate the message board for ESPN.

My Problem:
1 - I would like to have greater control of the visual output, and include the date/time of the post.

2 - The RSS feeds do not update as often as I would like on either of the league pages. I think this deals with a cronjob, but have no idea how to set it up

So:
What software can I use to create my own RSS to JS and RSS to HTML (iframe) to insert the RSS feeds into these sites with a refresh rate of 1-5 minutes or less? And what is the process. I am pretty much a noob when it comes to everything on the internet backend, but I can follow directions and ask relevant questions.
