Actionscript 3 XML data for Textboxes in Movieclip

Hello all, I am working on a advent calendar and I know that I have a specific number of days (Nov 26th - Dec 26th) I have a XML document that will pull data from a database and each day will fill out the contents of the XML. Anyways I have built a calendar that has all the days in it and assigned a generic instance name of ad22, ad23, ad24 etc... I did this because I can take the day in the query and just get the numeric value 22,23,24 etc.. The XML file will bring that value in a variable called listdaynum.

Then I want to ad something like:
var xday = ["add"+listdaynum];

What I want to then be able to do is this in a loop
xday.message.text  = txtmessage;

I get error's when trying this approach. Most blogs say to create an array and  but this gets more complicated. Any helpe would be greatly appreciated.
