[Python-Dev] folding cElementTree behind ElementTree in 3.3 (original) (raw)

I'm happy to stand up as an example of someone who uses a custom Element class. My specific use case is loading the project Gutenberg database, which is a 210MB XML file. I created a custom Element class which I use for the top-level element (a custom elementfactory passed to TreeBuilder distinguishes between the top-level element and all others). The custom Element class doesn't add children, so it keeps ElementTree from storing all of the elements its seen so far. On a system with 1 GB of RAM, there was no other way to get the file to load.

So, I would be one of those people who would flood in the complaints. :)

Andrew, could you elaborate on your use case? Are you using cElementTree to do the parsing, or ElementTree (the Python implementation). Can you show a short code sample?
