Pretty printing XML in Python

Question

What is the best way (or are the various ways) to pretty print XML in Python?

Answer 1

I had some problems with minidom's pretty print. I'd get a UnicodeError whenever I tried pretty-printing a document with characters outside the given encoding, eg if I had a β in a document and I tried doc.toprettyxml(encoding='latin-1'). Here's my workaround for it:

def toprettyxml(doc, encoding):
    """Return a pretty-printed XML document in a given encoding."""
    unistr = doc.toprettyxml().replace(u'',
                          u'' % encoding)
    return unistr.encode(encoding, 'xmlcharrefreplace')
