XML help Needed badly

I have never used XML and I am trying to use a menu using XML
I want the buttons in the menu to link to an external swf and load in the main movie in a container movie clip.

here is the code where do I put the loadMovie action?

</button>
<button name = "main button">
<subitem name = "button1" location="movie1.swf"></subitem>
<subitem name = "button2" location="movie2.swf"></subitem>


Do I even put the loadMovie action in the xml file???

Thanks for taking the time to read this and I appreciate any help...

Ok,
I guess I am not describing my problem..

I am using a menu component that uses xml to load the buttons.. I can't get the buttons to load my swf in a movie contaniner clip. I am not sure how xml works.. So just asking for a tutorial on xml somwehere or if someone has used the BounceMenu component.

thanks..
