如何从本地来源将KML添加到OpenLayers地图？

Question

I am looking at this example from openlayers themselves. You can see the source by clicking on the "kml-layer.js" link at the bottom. The source code when i do this looks like this:

var map = new OpenLayers.Map({
    div: "map",
    layers: [
        new OpenLayers.Layer.WMS(
            "WMS", "http://vmap0.tiles.osgeo.org/wms/vmap0",
            {layers: "basic"}
        ),
        new OpenLayers.Layer.Vector("KML", {
            strategies: [new OpenLayers.Strategy.Fixed()],
            protocol: new OpenLayers.Protocol.HTTP({
                url: "kml/lines.kml",
                format: new OpenLayers.Format.KML({
                    extractStyles: true, 
                    extractAttributes: true,
                    maxDepth: 2
                })
            })
        })
    ],
    center: new OpenLayers.LonLat(-112.169, 36.099),
    zoom: 11
});

It seems that this will only work if sourcing a kml via HTTP, but what if I want to source it from my own hard drive while I work on the map itself? I can't seem to find much documentation on how to do this, can someone help out?

Thanks

While this functionality requires hosting, there is a small work around. If the data is public, and you don't want to use Python, you can create a free google website, and upload the KML to there and direct a link to it. This used to work for me.
