Re: [libvirt] [PATCH 3/4] python: optimize SAX xml parsing event handler

close(), getmethodname(), cdata() are not standard methods from parent class ContentHandler and not being used anywhere in codes, so remove them. In docParser, actually, we are overloading three parent methods startElement(), endElement() and characters(), so I rename back three of these method names for example from start() to startElement() which makes it simpler to read. make other improvements in codes.
