XML file reverts to original file after save - Why?

Question

Hi guys,
I'm working with a little bit of XML and have questions, first here are my steps:
1) Load XML
2) Append to XML
3) Save XML using PHP
pretty simple, right?
Well, why when I load the same XML file does it read the file without the appendend nodes I just added?
I can open the XML file in Dreamweaver and see the appended nodes, but once I load the XML back into the .SWF, it clears the appended nodes and only reads the original nodes again..... simplified version like this:
Original file:
<?xml version="1.0" encoding="UTF-8"?>
<people>
     <person>
          <name>Steve</name>
     </person>
</people>
Saved file, readable in Dreamweaver:
<?xml version="1.0" encoding="UTF-8"?><people>     <person>          <name>Steve</name>     </person>     <person>          <name>Mary</name>     </person></people>
When .swf file is closed and reOpened to save another person it opens:
<?xml version="1.0" encoding="UTF-8"?><people>     <person>          <name>Steve</name>     </person></people>
My .swf is local at this point and PHP and XML files are on a server running PHP5.
Apparently the PHP script is correct because it DOES save the file correctly. I can save as many <persons /> as I want. But when I close the Flash .swf the URLLoader reads the original XML data again. Not sure how that's possible?
When I change the location of the XML to load into the URLLoader it changes so I know it's reading the same file I saved to.... I'm so confused.
Hope this is enough detail for someone to help me,
Thanks,
Sky

Wish it was possible to handout additional answer points based on (time spent trying to figure it out) vs. (helpfulness of answer).
To bad we couldn't some how accrue points when learning and give to you guys that help us out.
Then Adobe could have a redeem points system where you guys get free stuff in lieu of helping us all learn their programs.
Thanks again,
