[Mapserver-users] Getting attributes of tiled shapefile data

[Sean Gillies]

Steve,

Thanks for the tip!  There's also a 'values' attribute for the
SWIGged shapeObj, but it's not as useful since it returns a
SWIG pointer rather than a hash.  You did point me in the right
direction.

Best I could come up with uses Python's list comprehensions.

     res = layerobj.getResult(j)
     shp = layerobj.getShape(res.tileindex, res.shapeindex)
     items = [layerobj.getItem(i) for i in range(layerobj.numitems)]
     values = [s.getValue(i) for i in range(layerobj.numitems)]
     cfcc = values[items.index('CFCC')]

Not as nice as PHP ... yet one more thing to catch up with.

thanks again,
Sean
