Specifying a parseObserver with KmlFile::CreateFromParse method?

[Bruce Forsberg]

Is there a way to specify a parseObserver with the method
kmlengine::KmlFile::CreateFromParse?

I have a kml/kmz string of data and I need to get a KmlFile and parse
the elements at the same time. I am currently doing this in two steps
which seems to parse the stream twice. For large streams this is to
much of a performance hit.

Thanks
