Armin Ronacher evaluated different models for generating XML versus JSON and faced issues with models returning invalid XML.
Ronacher required a sloppy XML parser and asked Claude, the AI, to develop a proper XML library from scratch.
The AI created a parser with 1100 lines of code, 1000 lines of tests, CI setup, PyPI publishing setup, a logo design, reconfigurations, and more.
The result, 'sloppy-xml', is on GitHub and PyPI, with Ronacher highlighting it as an experiment rather than a recommended practice for serious Open Source libraries.
