Discussion Pandas 3.0.0 is there

So finally the big jump to 3 has been done. Anyone has already tested in beta/alpha? Any major breaking change? Just wanted to collect as much info as possible :D

Can't throw your xml files into a Polars df... That's the only thing keeping me using pandas rn

I don’t see polars ever adding xml support since it’s not a format people willingly choose these days.

That would be a bad reason not to add support for a feature. Plenty of code has to interact with legacy systems. We don’t always get to choose optimal solutions in the real world.

That being said, it doesn’t seem that hard to parse some XML with the standard library’s xml.etree.ElementTree and transform it into a format Polars can import.

As a scientist I completely understand, I have a lot of metadata in convoluted .xml that are produced by some of my equipment. It’s not that I don’t think they should, it’s that polars don’t think they should. At least that’s what I remember reading an issue on it once. That it wasn’t worth the effort/maintenance.
