guid element breaks my rss php code

[romeoyankee]

hey guys.. great site by the way. 

 

First of all I am a relative php newb but am able to read and search and learn on my own.  In saying that I have read and searched everything I think I can so I will ask here...

 

I am using a script called magpierss which is supposed to parse rss files and then using my code I can combine multiple rss feeds and then create a new rss feed from that..

 

I seem to be having a problem with my code though...  Occasionaly there is a link in an rss feed that seems to break the php code i have written somehow.

 

Best way I can explain it is this..  if you go to the site.. http://www.cyow.ca/magpie/indextest2.php you will see that it might be working or not.. If its not run it through a feed validator

 

I am combining about 9 rss feeds into 1. Each individual rss feed shows up fine and will validate correctly on its own. 

 

Once I combine the feeds and create my new feed the new rss feed seems to break.  I mean that when you go to the link http://www.cyow.ca/magpie/indextest2.php  you only see the first few stories being displayed , if that, up until the feed gets broken.  I have set it so there should be 30 stories.  If you were to view the source though everything looks fine.. 

 

It wont validate because I think it has something to do with a guid element.. I dont really know what that is though.

here is the script I am using to call all this info
