try this one
http://www.maxpc.co.uk/tutorials/default.asp?siteid=7§iontypeid=7&subsectionid=706&subsubsectionid=530&pagetypeid=2&articleid=36731&page=1
it doesn't use ajaxlib but you could see how it fits in, the result
sending code is as simple as
<?php
header( Content-Type: text/xml);
echo <?xml version=”1.0” stand
alone=”yes”?><postCode><city>
Bath</city><county>Avon</
county></postCode> ;
?>
I don't write my own raw XML but rather use the SimpleXML Class
I must admit I had a chuckle over "non visual server application in PHP"
since all PHP applications are non visual
