Hmm, the positional info of sax isn’t very good.
I’m not a giant fan of sax, it’s very loose, pretty big.

I think I’d like to switch to something else. Perhaps https://github.com/rgrove/parse-xml. Seems fast. Halve the size. Well-maintained and modern. Doesn’t expose positional info from what I can see though

Another parser is probably a good idea. I encountered this error when working on a converter from lezer-xml to xast.

I have it basically working: https://github.com/siefkenj/typescript-xml/tree/main/packages/xml/src/lezer/lezer-to-xast

The only differences between fromXml and what I just made are correct positions and no errors (lezer is designed to parse no matter what, though it can be instructed to throw on the first error).
