[mapserver-users] Re: Dynamic data loading using Google maps andMapserver

[Jim Strevinas]

http://www.dyasdesigns.com/geoxml/gmlusa.htm

It makes use of an API plugin called geoxml that can load XML data which can be produced by
a WFS server. In the source code, a static GML file is used but a google search shows that it can 
connect to a live WFS server using the URL.
