Martin,

Thank you for your reply.
Here is what I'm trying to do... hoping I can stay within the .xml format.  
That is why I'm in your forum, rather than PHP.  I'm trying to figure out if 
it is possible to dynamically link parts of .xml nodes to a separate file in 
the same directory, without disturbing the rest of the nodes in the .xml 
format.

We have feeds offered directly off the site, but also via subscription feed 
and subscription email feed via Feedburner (now with Google).  We have 
hundreds of subscribers  for the different venues, so I don't want to disturb 
the .xml extension that Feedburner is set to if possible.  

Every week I use a Find / Replace to replace the <pubDate>, <lastBuildDate>, 
the starting date (would be "April 3, 2009" below) and the week of date 
(would be "Week of April 3rd - April 9th" below).

Then I also have some common feed <description> information that I have to 
open each feed and do a cut and paste and save.

Not only is this redundant and time consuming, but more importantly, leaves 
me open for mistakes.  So I'd like to do the common information mentioned 
above more dynamically.
I've tried to figure out how to use dynamic linking in the parts of the .xml 
feed files that would change weekly.... linking to a master file where I'd 
make the weekly changes necessary, but I've not had much success.

Here are some samples, and again I thank you for your time and knowledge.

The unique information for each feed I've replaced with UNIQUE FEED INFO.

The common information I've replaced with COMMON FEED and put between -------

The actual feed that would be displayed would follow this format... I've 
reblocked and shortened the number of items for clarity.

<?xml version="1.0" encoding="utf-8"?> 
<rss version="2.0">
