Add a MC after dynamic text

Is it possible to add a MC after the end of some dynamic text that is loaded via XML?

I am making a News type scroller. The lines of text vary, sometimes there are 3 lines of text…2…4…etc.

I wanted to make a button MC (it will consist of an arrow graphic and static text) that will be placed at the end of the text in the text box.

I was thinking I would be able to do it like this somehow…

temp_mc.[COLOR=#000000]tmytext[/COLOR] = obj.[COLOR=#993300]text[/COLOR];
temp_mc.[COLOR=#000000]item_txt2[/COLOR].[COLOR=#993300]htmlText[/COLOR] = temp_mc.[COLOR=#000000]tmytext[/COLOR]+ [COLOR=#0000ff]"<br>"[/COLOR] + [COLOR=#993300]movieclipHere[/COLOR]
