title: OpenLayers GeoRSS parsing - All points on top of each other
body: <p>I'm following an OpenLayers tutorial from OpenGeo, and am struggling with a vector layer which reads a GeoRSS encoded XML file of earthquake locations - which seems to be used a lot in these sort of tutorials.  The maps produces a single point (at 0,0) which on closer examination appears to be all the points in the file stacked on top of each other so clearly something is going wrong between the translation of the point in the XML and OpenLayers.</p>
  
  <p>Here's the code:</p>
  
  <pre><code>var geographic = new OpenLayers.Projection("EPSG:4326");
  var mercator = new OpenLayers.Projection("EPSG:900913");
  
  var world = new OpenLayers.Bounds(-180, -89, 180, 89).transform(
      geographic, mercator
  );
  
  var center = new OpenLayers.LonLat('.$centerMapLat.','.$centerMapLon.').transform(
      geographic, mercator
  );
  
  var options = {
      projection: mercator,
      units: "m",
      maxExtent: world
  };
  
  var map = new OpenLayers.Map("map-id", options);
  
  var osm = new OpenLayers.Layer.OSM();
  map.addLayer(osm);
  map.addControl(new OpenLayers.Control.LayerSwitcher()); 
  map.setCenter(center, 2);
  
  var mapdata = new OpenLayers.Layer.Vector("Map Data", {
      strategies: [new OpenLayers.Strategy.Fixed()],
      protocol: new OpenLayers.Protocol.HTTP({
          url: "7day-M2.5.xml",
          format: new OpenLayers.Format.GeoRSS()
      })
  });
  map.addLayer(mapdata);

  <p>It doesn't seem to matter what value is placed between the  tags, or how many fields I cut out, the point always appears at 0,0.  I can move the spot by editing the coordinates manually in firebug - this is what is rendered in the html for each point:</p>
  
  <pre><code>&lt;circle id="OpenLayers.Geometry.Point_424" 
      cx="4.738678387182473" cy="237.58907791425827" 
      r="6" fill="#ee9900" fill-opacity="0.4" stroke="#ee9900" stroke-opacity="1" stroke-width="1" stroke-linecap="round" stroke-linejoin="round" stroke-dasharray="none" pointer-events="visiblePainted" cursor="inherit"&gt;
  </code></pre>
  
  <p>I strongly suspect I have done something wrong, so would appreciate a sanity check</p>
