[OpenLayers-Users] Highlighting Feature on KML Layer

You will note that google isnt good about providing that functionality 
themselves in their products. KML is a very flexible format. You can 
define attributes for a featureset in the set header and then provide 
just the data for the feature ( as you would for a "normal" layer), but 
you can also have attribute and data for each feature (ie each feature 
could have different attributes). Furthermore the KML could just be a 
network link.

In short, I dont think it is implemented in OL but maybe others would 
prove me wrong. If you are stuck using KML vector files, then I think 
you will need custom code to pick your way through a loaded KML layer 
feature entries. If you have option of not using KML than I would 
strongly consider it. If your data is in say geoserver then you can 
create a WFS kml link to view in GE from your web application but using 
KML directly is slow and limited.
