Thank you.  That's it.  I was opening the layer in the wrong spot.

|     results = layer.getResults()
|
|     if results:
|
|         # open layer in preparation of reading shapes

|             feature = layer.getFeature(r.shapeindex, r.tileindex)
|
|             # Iterate over feature attributes
|             for j in range(layer.numitems):
|
|                 att_name = layer.getItem(j)
|                 att_val = feature.getValue(j)
|
|                 print att_name, att_val
|
|         # Close when done
|         layer.close()
