RSS incoming feed edit!

Hi Guys, got a bit of a RSS problem.. I have a feed coming in from a blog and a webshop to my wordpress site, but I don't like the fact it brings in the date with the posts:

Tue, 05 Jul 2011 20:06:00 +0000: (title) (poster)

Id like to keep the title and the posters however! The php code for the plugin is a little confusing:

<?php
/*
Plugin Name: RSS in Page
