If "traverse" is what you need precisely, the absolutely best way to do is System.Xml.XmlReader. Is you want manipulation of the data, simplicity and not the best performance, using DOM will be easier, see the class System.Xml.XmlReader.

Please see Microsoft help on the topic and the samples; they are clear enough.
