Actionscript 3 :: Replace Nodes In Xml, From A InputTextField?

I have a inputTextField, and in my inputTextField in my GamePage class i want to be able to take the text that you should be able to write in the inputTextField, and replace the text from the inputTextField with my nodes in my xml-fil. In my Xml class above I want to have that code that converts the text from the inputTextField, ex. If i write "monkey" in my inputTextField, I want to replace {ANIMAL} node in my xml-fil with monkey.

package
{
import flash.display.MovieClip;
import flash.display.Sprite;

[Code]....

There was once a {ANIMAL} who came from {CITY}. {ANIMAL} lived in a small little red julhus, just like Santa does. {CITY} also had her Santa Claus, and his name {NAME}. {ANIMAL} and {NAME} was in fact best friends for ages ago, and they lived in the same little red house.
