[msmitherdc]

The StyleUrl value is not available when exporting kml to other formats and it is a useful attribute to export.

styleUrl shows up as featurestyle as per the ogr feature style spec.

I did not add this because OGR already has a way of dealing with feature style in formats that do not support it.

the folowing is from ​http://www.gdal.org/ogr/ogr_feature_style.html

2.9 Using OGR SQL to transfer the style between the data sources

We can use the OGR_STYLE special field to extract the feature level style, and ogr2ogr can be used to transfer the style string between the data sources according to the following example:

ogr2ogr -f "ESRI Shapefile" -sql "select *, OGR_STYLE from rivers" rivers.shp rivers.tab

Without specifying the length of the style field the output driver may truncate the length to a default value. Therefore it may be necessary to specify the target length manually, like:

ogr2ogr -f "ESRI Shapefile" -sql "select *, CAST(OGR_STYLE AS character(255)) from rivers" rivers.shp rivers.tab

OGR is aware of using the OGR_STYLE field if exists and OGRFeature::GetStyleString will return the value of this field if no style string have been specified programmatically.

Works perfectly. Never mind then. Ticket closed.
