Please Help with XML input file

I created a flash swf with AS3 and i am loading the data via XML. I have a background that needs to load and I also created a box in which I can change the color via XML. I am have problems writing the XML code. Could someone please help. I'm brand new to this so I don't know if i'm even close. Here is the xml info i have so far. thanks

<data backgroundColor="0x202020" width="400" marginTop="150" marginBottom="150"><![CDATA[<p align="left">COPY GOES HERE<br><br></p>]]>
</data>

<backgrounds switchDelay="6000">
<image allowScaling="true">background_images/image1.jpg</image>
</backgrounds>
