It appears you're using MS IE7, which has an aggressive caching
policy. That means that when your page gets to this line
GDownloadUrl("phpsqlajax_genxml.php", function(data) {
it will happily retrieve the XML from its cache.
You can get round that by adding a parameter which changes the URL
each time, so that IE thinks it hasn't already got the file and needs
to get it again, something like
"phpsqlajax_genxml.php?dummy="+(new Date())
Retrieving the file from the browser address bar refreshes the version
in the cache, which is why that works at the moment. Browsers with a
less aggressive policy (like Firefox) generally don't need the
changing parameter.
