I have been looking at the available Elixir/Erlang libraries for working with XML and cannot seem to find something that can do everything Nokogiri (Ruby) does. I have come down to sweet_xml for parsing xml and erlsom for validating xml. I could use xml_builder to build xml or even erlsom. I have…

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 d…

@chulkilee Does xmerl do xml schema validation? I briefly looked at it, but did not see that it did.

Oh I don’t need xml validation so I didn’t check that out. However quick google gives me xmerl_xsd which should except xmerl form :slight_smile:

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. :slight_smile:

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.

I’ll keep looking into this and post back if I find some new info.

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 …

How did you setup sweet_xml to parse XML into a hierarchy of structs? I’m trying to get it using the @schema and i don’t know how to nest more complicated structs

Check out GitHub - chulkilee/ex_scems: A Sentinel Cloud EMS Web Services wrapper in Elixir · GitHub . 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 :slight_smile:
