As far as OpenLayers is concerned, that is the attribute. This data is
ulikely to be structured in any more useful way. You'll need to use
regular rexpressions or something similar toparse the data out of that.

If the data is included in some other tag in the KML as well, such as
ExtendedData, you may have more options. you might check that first, but
I wouldn't be surprisd if it doesn't.
