Flash and Javascript Variables?

I have a text file at a remote URL which is populated by a javascript statement.
The text file looks like this:

document.write(’ 92.0 ');What I want is to take the 92 and populate a dynamic text box on thestage called winNumber with it. Here’s the code I’m using for that:myFile = new XML();
myFile.onLoad = function() {
var myNumber = myFile;
_root.winNumber.text = myNumber;

}

myFile.load(“http://www.webaddresshere.com/text.txt”); This loads in the txt file just fine, but it loads in everything.Is there a way for me to lose the "document.write(’ 0 ');"and just send the “92” to the dynamic text box?Help is much appreciated. Thanks,Haig
