*sigh* Okay, this is not very friendly at all: $VAR1 = { Document => { AbstractFeatureGroup => [ { Placemark => { name => 'YAPC::EU 2008 venue', description => 'YAPC::EU was held at the Copenhagen Business School, 13-15 August 2008', Point => { coordinates => [ '12.530516,55.681597,0' ] } } } ] } }; Is there a way to clean this up, so that substGroups will auto-resolve, instead of being embedded into the tree?

The schema which defines KML files is far from easy. The data-structure produced/required by Geo::KML follows the quirks of the schema, without offering higher level translation to some nice object model. It is *not* difficult to create an object model on top of this, but I did not take the time to do that. For now, I only want a valid XML message, that's all. One of the reasons is that these KML messages are structurally a mess. Not designed but grown. And nearly all official examples of KML I have tested work in GoogleEarth, but do not validate against their own standard. The complexity with "AbstractFeatureGroup" will probably only show-up in one spot in your program. Not that horrible. -- Regards, MarkOv ------------------------------------------------------------------------ Mark Overmeer MSc MARKOV Solutions Mark@Overmeer.net solutions@overmeer.net http://Mark.Overmeer.net http://solutions.overmeer.net

The last "trace" message relates to the trace. The trace line which contains the Placemark is produced for an other node. -- MarkOv ------------------------------------------------------------------------ Mark Overmeer MSc MARKOV Solutions Mark@Overmeer.net solutions@overmeer.net http://Mark.Overmeer.net http://solutions.overmeer.net

All the more reason for some examples (per the other bug). Again, I'm not bitching about your code, just trying to help out. Don't mistake the frequency of these bug reports as that, either. Figured it's better to capture these, instead of working around it and not telling the dev. You may close this ticket.
