Any luck running on a large file? My backup file is 2.1GB. I tried to add:
from lxml.etree import XMLParser, parse
and then change
tree = etree.parse(INPUT_FILE)
to
p = XMLParser(huge_tree=True)
tree = etree.parse(INPUT_FILE, parser=p)
After cleaning the file as described above, I get the following output:
$ python3 extract-python3.py input/sms-20190505085947-clean.xml output/PixelXLMMS/
[*] Parsing : input/sms-20190505085947-clean.xml
[*] Job done (0 files created)
[*] Output folder : output/PixelXLMMS/
I'm also struggling with this on python3 / windows 10.
Any luck @nicksears?
Thanks for the code! I've modified it for my use to update "null" file names to the timestamp instead. I also set the file modification time to the MMS date timestamp. The other change I made was to parse messages individually instead of parsing the whole file at once. This allowed me to get through a very large backup.

This was a lifesaver! many thanks for porting to python 3 !
This is great! I just ran the newest version (posted by @bumpaneer) on a 600MB xml file and it worked wonderfully. I was about to start writing something to do the same thing but I wasn't looking forward to it :) Thank you.
Do you mind if I link to this gist from a Stack Exchange question?

Ported to Python 3. It works now!
