yes that's reasonable, but the LIBKML driver should already do that :
OGRStyleSymbol *kml2symbol (
IconStylePtr poKmlIconStyle,
OGRStyleSymbol *poOgrStyleSymbol)
{
if (!poOgrStyleSymbol)
poOgrStyleSymbol = new OGRStyleSymbol ( );
/***** id (kml icon) *****/
if ( poKmlIconStyle->has_icon ( ) ) {
IconStyleIconPtr poKmlIcon = poKmlIconStyle->get_icon ( );
if ( poKmlIcon->has_href ( ) ) {
std::string oIcon = "\"";
oIcon.append ( poKmlIcon->get_href ( ).c_str ( ) );
oIcon.append ( "\"" );
poOgrStyleSymbol->SetId ( oIcon.c_str ( ) );
}
}
And the reverse code also exists.
