Title: How do I get around a inconsistent collection in an xml document

The subject may not do well to explain, so I hope the xml example will do.

The hierarchy of the asset field makes it appear that it would a collection of assets with the exception of the featureId/platformId .  Is there a way to get a different field name instead of looking for that exact name?  I code for the featureId, so when it gets to the platformId, I get an error.  Please let me know asap,

Thanks,
Jason
