 var wfs = new OpenLayers.Layer.Vector("States", {
        strategies: [new OpenLayers.Strategy.BBOX()],
        protocol: new OpenLayers.Protocol.WFS({
            url: "http://ian01.geog.psu.edu/geoserver/wfs",
            featureType: "states",
            featureNS: "http://www.openplans.org/topp"
        })
    });
Loads the features from the WFS, you can then do anything you want
with the wfs.features array.
