[gdal-dev] GML elevation

[Nikolaos Hatzopoulos]

System.out.println("Elevation"+poDS.GetLayerByIndex(0).GetFeature(0).GetFieldAsString("elevation"));

ERROR 1: No such a field 'elevation'

I am refetching to find where in the tree is the elevation :) yes I know is
expensive

does it has to do with the version I am using? I am using 1.7.2
