How to define KML Name element when using QgsVectorFileWriter?

Question

I am trying to use QgsVectorFileWriter to write a kml file from an active layer in QGIS, but cannot figure out how to define the KML Name element (called NameField in the QGIS save-as GUI) to correspond with a field in my shapefile, which is called "TYPE".

This code does not cause an error, but I cannot figure out how to define StringList to specify that the NameField column name is "Type":

QgsVectorFileWriter.writeAsVectorFormat(layer, kmlPointFile, "UTF-8", None, "KML", onlySelected = 0, datasourceOptions = StringList)

Answer 1

I have switched to using gdal through python - my solution is:

cmd = 'ogr2ogr -f GPX -dsco NameField=TYPE {0} {1}'.format(outFile, inFile)
os.system(cmd)
