The same function is also available for vector layers;

I presume you will have set your kml layer up somewhere along the
lines of;
var myKMLLayer = new OpenLayers.Layer.Vector("KML", {
strategies: [new OpenLayers.Strategy.Fixed()],
protocol: new OpenLayers.Protocol.HTTP({
url: "whatever",
format: new OpenLayers.Format.KML({
extractStyles: true,
extractAttributes: true,
maxDepth: 2
})
})
};
Then all you do is call
map.zoomToExtent(myKMLLayer.getDataExtent());
That work for you?

Do you have, or know where I could find, an example of this being

Is there an easy way to center and zoom the map automatically
based on
the placemarks that are on it?I have it so that one can filter
placemarks based on user input but I'm not sure how to dynamically
update the map to fit the newly filtered content.Thanks for any
insight
that can be given regarding this matter.
An OpenLayers.Layer.Markers instance, has a method called
getDataExtent() This should do most of what you want.
It's not automatic, though. You'd still need to call
map.zoomToExtent() after the markers have been added to the layer.
