Re-useable swf / importing text

Im creating a flipping boook for a friend, who will occasionally need to update pages / text, but without using flash.

All of the text for the individual pages is stored in a single text file (pageText.txt) in the format:

page1=Page One's Text
page2=Page Two's Text
page3=Page Three's Text...etc

Each page is a clone of a single .swf which will simply load the relevant text.
I’ve hard coded this to get page 1’s text, which works fine:

loadData = new LoadVars();
loadData.onLoad = function() 
{
  page_txt.html=true;
  page_txt.htmlText = this.page1;
};
loadData.load("pageText.txt"); 

However this would mean changing

page_txt.htmlText = this.page1

for each individual .swf. Is there any way of using the filename (page1.swf, page2.swf) to set the ‘this.pageX’ statement?

Cheers

Chris

As there doesn’t seem to be any other options i’ve gone for a big switch statement which uses the number from the .swf file (page1, page2 etc) to decide which text to load.
