Personally I think using a SAX DocumentHandler for this has several
advantages, especially in Python:

 - it's easier (especially when dealing with attributes)
 - it makes it much easier for someone to intercept the output stream
   and make some other kind of use of it[1]
 - you get escaping automatically
 - you can easily get pretty-printing if you want it

    through a parser filter before going to disk, building a DOM
    structure etc.
