I have attached the XML data in question at the end of this post.
I don't understand what is between <TripData> and </TripData>.  When i
talked to the publisher of the XML document, he says: "you will have to use
childattributes to access the attributes of the <TripData> element".

I've got following XML structure
<ROOT>
 <DATASET>
    <ID>1</ID>
