Why can't I load sent/received data into an xml array?

I have been using kglad's send/receive code:

var sendLV:LoadVars=new LoadVars();

var receiveLV:LoadVars=new LoadVars();

receiveLV.onData=function(src:String){

trace(src);

//etc. . . .

The code apparently functions well because the "trace (src);" line generates what looks like perfectly formatted xml text in the output window:

<?xml version="1.0"?>

But after trying for 2 days and 50 different approaches I have been unable to get the "received" data to load up on a page.

Any ideas or advice?

Thanks.
