Its actually counting the nodes at differet levels in that example.

Dictionary<string, int> counts = new Dictionary<string, int>();
foreach (XmlElement element in dom.DocumentElement)
{
    if (!counts.ContainsKey(element.Name))
    {
        counts.Add(element.Name, 0);
    }
    counts[element.Name]++;
}
