This version simply enables the POST method to be enacted by both Mozilla browsers AND IE
through javascript.
There are NO changes to either the encoding function, or the dynamic creation of the XML string.
The only changes are replacement of the Mozilla DOM functionalty with conventional dynamic
object creation functionalty using the document.write method understood by most browsers.
A trivial hack to be sure, but nevertheless enormously usefull to me.
This method is of use if you need to pass a variable to the XML. For instance, I can pass a
zip code to the XML on the fly thusly : doSubmit(zipcode_1).
