I've been playing with Aaron Swarz's XML Tramp as an intuitive/pythonic way of processing XML. The model/syntax isn't explicitly documented, but from the source and (mostly) examples, this is what I've figured out:

XML Tramp Conventions

• Elements have a list of children '[]'
  • iterate over children: for child in doc
  • get first and second (splice) child: doc[0:2]
  • get named child element book: doc.book or doc['book']
• Elements have a dict of attributes '()'
  • test for an attribute COLOR: if 'COLOR' in doc.book()
  • get attribute COLOR value: doc.book('COLOR')
  • assign attribute value: doc.book(COLOR='blue')
• Namespaces (NS) are indicated with a period, the period indicates its not a literal value (as with quotes), but a namespace corresponding to an arbitrary but specified prefix
  • NS qualified elments now appear unquoted within brackets: doc[ns.book]
  • NS qualified attributes now appear unquoted within parenthesis: doc(ns.COLOR)
• To reserialize an object use print doc.__repr__(True)
