RSS and Atom headline feeds to a page

[Mouse]

I hope someone out there may be able to help me out here. I have been trying to pull a few feeds into my page from Blogger and a couple of other sources with mixed success. I have to date been using Aaron Dunlaps script RSS_Get [http://www.aarondunlap.com/?content=rss_get] and if you look to the bottom right of my page [http://mouse.nodstrum.com/blog_links.php] you’ll see that under the heading of ‘The After the Mouse blog’ the feed from Aaron’s blog comes through just fine but all the others are, well useless! And that’s because they’re Atom feeds from Blogger…

I will admit I know zip about the workings of XML weather its Atom or RSS so can anyone tell me where I need to make alterations to the code to make it Atom friendly

<?php

  #==========================
  # The following line declares how long to wait before reloading the RSS feed.
  # Keep in mind, many sites discourage people from pulling its feed more often than 30 minutes.
  # For example, Slashdot.org may ban your server if it tries to load the rss feed too often.
 
  # You may change the below line.
  #==========================

  $minutes = 30; //How often to update the image. 0 indicates that image updates every time it is called (heavy strain on bandwidth & server)

  #==========================
  # The next line is what directory to dump the htm files generated by this script.
  # It should be relative to the location of this script, and it *MUST* have a trailing slash if it's a seperate dir.
  # If you want the files to be dumped in the same dir as this script, set it to ""

  # You may change the next line
  #==========================
 
  $filename = "rss/";
 
  #==========================
  # The next 4 lines are default settings for the script to use, if they are not set prior to including this script
  # You may change the next 4 lines.
  #==========================

  $default_url = "http://www.aarondunlap.com/rss.php?mode=hl"; //URL for the RSS/XML feed you're subscribing to.
  $default_displayname = "|| aarondunlap.com ||"; //Title to appear before headlines. Should be feed-specific
  $default_number = 5; //How many headlines to display. If you set it higher than the ammount of headlines, it will stop there
  $default_target = "_self"; //Target for headline links. Options: "_self" and "_blank"

  #==========================
  # The next line is whether or not the script should auto-update.
  # If enabled, the script will check to see if a newer version of this script is available and will
  # automatically download and install it. Your current version of the script will be backed up  in your $filename
  # directory.

  # If you have manually edited this script, you should disable this. Otherwise, it is recomended that you enable it.
  # Also note, your customized settings (default_url, default_displayname, filename, etc) WILL be kept during
  # auto-updates. Alterations to the actual function code (beneath) would be overwritten in an update.

  # During updates, your existing script is backed up into the $filename directory as "backup_[date]_(time).php"

  # You may change the next line
  #==========================

  #                the default is FALSE, which wont truncate
  #                at all.
 
  #                You may use $trunc when calling this script
  #                to define the truncation for specific feeds
 
  # $default_delim is what character to cut off the headline at
  #                for example, if your headlines contain useless
  #                data at the end, like "(via Reuters)", setting
  #                the delimiter to "(" will stop that from showing.
 
  #                You may use $delim when calling this script
  #                to define the truncation for specific feeds

  # awake enough to do it? Maybe take a nap, rethink things, try again.
