Good to know for migration. The reason for switching to Python is just
to reduce system requirements of my tool. The prototype works fine with
Is the xml.dom entirely -with all subpackages/modules- available under
the same package in Python? Currently I use from PyXML particularily
# (1) for reading/parsing data from XML:
from xml.dom.ext.reader import Sax2
# (2) for building/manipulating DOM tree:
from xml.dom.DOMImplementation import implementation
# (3) for serializing data to XML:
from xml.dom.ext import PrettyPrint
AFAIK, I can replace (2) with the respective features in Python, seem to
have still the same structure and names, at least those I use.
I guess (3) can be replaced by a to_xml() method (?) I noticed
somewhere, but I need to look again.
There is just (1) which leaves me with some doubt and head-ache what to
do. I wonder which Python lib would be the appropriate replacement for
the Sax2 reader. Nota bene, that I was confused by the name "SAX" since
I use it as described here:
in order to get a DOM tree from the XML file which I can than walk
through - I don't care the events... but I thought SAX is
event-driven?!? However, I need to switch to a tree-based XML parser
alternative on Python distribution.
