Yes, Meeseeks is very nice! I recently used it for a small scraper and it was faster and easier to use than anything else I looked at.

Note that it’s fast because it uses a NIF to wrap the Rust library html5ever. I installed Rust (using asdf), added Meeseeks to my deps and it just worked. But it’s good to be aware of the extra dependency.

If you don’t need validation and the XML can all fit in memory then the Meeseeks library has a FANSTATIC query interface into XML that puts anything else I’ve used yet to shame.

Check out https://github.com/chulkilee/ex_scems.

Basically I use SweetXml.transform_by/2 and then pass map into struct!/2.

I wrote it a while ago, so I may want to do it different way now though

I had the similar issue. I need to parse complicated XML into many structs with hierarchy (to provide good abstraction and functions on them), and also need to update XML (which is actually create new copy with changes, you know)

I’m using sweet_xml for parsing to hierarchy, but I think I have to deal with underlying erlang library anyway - probably xmerl format instead of erlsom, since xmerl looks like the built-in app in Erlang and probably be accepted by more libraries.

But yes, I miss Nokogiri style DOM manipulation and easy output (to_xml).

So would that be even better than sweet_xml. I will still need validation and the ability to build xml, but I could just use xmerl for that part.
