actually i'm trying to change the relationship 'is next sibling of' to
'is child of' throughout a document

my latest idea is to go to the end of the document, then walk it
backwards (for christmas?:-) towards this end i wrote:
---
walker = doc.createTreeWalker(doc.documentElement,NodeFilter.SHOW_ELEMENT,
None, 0)
while 1:
  print '1 '+walker.currentNode.nodeName
  next = walker.nextNode()
  if next is None: break
print '2 '+walker.currentNode.nodeName

which, given
---
<?xml version="1.0" encoding="utf-8"?>
<Game><A/></Game>

---
outputs
---
1 Game
1 A
2 Game

the loop has finished?
