Pass a Variable INTO Xml

I have an ActionScript in Flash and an XML file that are working together.

I've set up my variables and such, and then I want to loop through them and add something to each "record." So I can do something like this:

for each (var object:XML in xml.*) {

                  object.appendChild(<myId>my id is here</myId>);
                  trace(object);
      }

That will add a new line in each item like so:
<myId>my id is here</myId>

Now, I obviously don't want to write "my id is here" as the value between the <myId> tags. The problem is I want to do something using a foruma or method or something to get a unique value there.

For example,  I'd like to do something like this...

object.appendChild(<myId>object.childIndex()</myId>);


...where the theory is that it returns the child index number of the object, so the fist item  would be appended with <myId>0</myId> and the second would be <myId>1</myId> and the third would be <myId>2</myId> and so on and so forth.

The problem is that it's writing everything as a string. It's actually writing out <myId>object.childIndex()</myId> for all of them,

I even tried doing something in ActionScript first, where I'd go:

var i;

and then push a value into the i variable via an incremental loop and then I would try

object.appendChild(<myId>i</myId>);

But, again, it just writes in "i" and not the value of i.

I need a way to say, "Calculate this part between the brackets."

Can anyone help? Is it possible? Is there another way around it?

Here's an sample, it will append the new node. But see how we are concatenating string and variable.
---------------
var node:XMLList = new XMLList("<myId>" + i + "</myId>");
object.appendChild(node);
