Twitter-Feed : Takes twitter RSS feed, strips the "username: ", removes @replies

I have an RSS feed of a Twitter page on my website but I don't want the username of that Twitter's profile to be mentioned at the start of every message.

Currently the format is, "username: Twitter message", I want that simply changed to "Twitter message".

The code for the RSS is below, it would be greatly appreciated if anyone can think up some code that would eliminate the name from the messages.
