As this is turning into a rosetta code excercise, let me throw in C#:
var elems = XDocument.Load(path).Root.DescendantsAndSelf();
var attrs = elems.Attributes()
.GroupBy(x => new { Attr = x.Name, Elem = x.Parent.Name });
foreach (var elem in elems.GroupBy(x => x.Name))
Console.WriteLine("{0} {1}", elem.Count(), elem.Key);
Console.WriteLine();
foreach (var attr in attrs)
Console.WriteLine("{0} {1}/@{2}", attr.Count(),
attr.Key.Elem, attr.Key.Attr);
Though it would seem the GNU-ish way to solve this would be having a
tool that prints out all the element names and attribute/element paths
and then use, say, `sort | uniq -c` on it.
