Xmloxide

Okay so this is actually clever — xmloxide is an XML parsing library, but the real move here is the methodology behind it. The founder built it by feeding test suites from existing XML libraries into AI coding agents and letting them reverse-engineer the implementations. Anthropic and Cursor have been running these wild experiments where they task agents with rebuilding things like browsers and compilers from scratch, and now someone's applying that same approach to reproduce old open source libraries. It's less about the XML parsing (honestly, there are a dozen solid options already) and more about proving whether AI agents can actually recreate battle-tested software by staring at tests and guessing the architecture. The signal here is whether this method scales — if you can recreate a parser in an afternoon, what else gets democratized? That's the question worth watching.
