You can use the serialize method on the document node to get the
document as text (or on any other node to get a document fragment as
text):

  s = doc.serialize()
  # Use normal file writing mechanisms.

Or you could use the saveFile method to write to a file:

  doc.saveFile(filename)

I'd recommend using Python interactively to see which methods are
available on the document node:

  import libxml2
  doc = libxml2.parseFile(filename)
  dir(doc)

Indeed, until I started responding to your question, I hadn't noticed
saveFile, so there's a lot to discover. ;-)
