[OpenLayers-Users] KML Centroid

[Bill Schoolfield]

Hello,

I have a database application with lat/long and associated attributes in 
MySQL. MySQL extensions, are far as I know can't be used to compute a 
centroid.

Is there a way in OpenLayers to compute the centroid for a given vector 
layer that's obtained via a KML file? I see that there is a function 
that acts on geometry collections. Can that be used? If so I assume I 
have to iterate over the data obtained via the KML file to create this 
collection...

The whole purpose is to set the map's center and initial bounds.
