1. Please post a link to your map that shows the problem:
http://groups.google.com/group/Google-Maps-API/web/suggested-posting-guidelines
2. I have no idea what is wrong with your code as you didn't post a
link, but something like:
**** TOTALLY UNTESTED ***
var infoWindowContents =
GXml.parse(kml.getElementsByTagName("Placemark")
[i].getElementsByTagName("description")[0]);
should work.
