Why do this the hard way? Mapserver now can generate KML output.<br>Just create a KMLLayer on google maps API an it will do all for you.<br><br>The KMLlayer do the ajax request for you, setup the click handler on Map, setup the infoWindow events all in a two line call, support all simple features geometry types for vector data.<br>
<br>On mapserver side, setup the kml layer, bind an attribute to the kml name attribute that will de the infowWindow header.<br>For additional text on info window you can instruct mapserver to assembly an HTML template to the kml description attribute.<br>
? Can someone put an layer example for this case ?<br><br>Check out KML sample builder for details<br><a href="http://kml-samples.googlecode.com/svn/trunk/interactive/index.html">http://kml-samples.googlecode.com/svn/trunk/interactive/index.html</a><br>
<br>and Mapserver<br><a href="http://mapserver.org/output/kml_output.html">http://mapserver.org/output/kml_output.html</a><br><br>and Maps API KML<br><a href="http://code.google.com/intl/pt-BR/apis/maps/documentation/javascript/reference.html#KmlLayer">http://code.google.com/intl/pt-BR/apis/maps/documentation/javascript/reference.html#KmlLayer</a><br>
<br>If mapserver options do not meet your requires is very easy to create KML without Mapserver at all.<br>The problem now is turning into to force mapserver do what google requires.<br>If mapserver is becoming hard to do it, you make your logic without it.<br>

The forward could be to a JavaScript file with an empty object. Browser should follow ok...<br>
