  This sounds a lot like
  http://mail.gnome.org/archives/xml/2004-October/msg00101.html

I think the solution is explained at
  http://xmlsoft.planetmirror.com/xmlreader.html#Extracting1
You can either:
  - loop with for all values of 0 .. AttributeCount() - 1
    and use MoveToAttributeNo(no) then use Name()/Prefix()/NamespaceUri()...
  - or use MoveToNextAttribute()
    and similary use Name()/Prefix()/NamespaceUri()

 the small Python example in that doc shows the second one.

I did not design this API, this is directly copied from C# xmlReader API.

  Hum, there is no "bindings" for C as the API is C. all this can be done
at the C level.
