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 not found a library other than erlsom that does all three- parsing, building and validating. I am also an Elixir newbie so I could be missing something.
What would you all suggest? Using a combination of libraries as mentioned above or is there something else out there I’m missing?

TNX! Shall explore this path

Most public functions in that file take an optional
options_list()argument, which can include afetch_fun:https://github.com/erlang/otp/blob/845adc7375b221359e387e3837fb5b2242fecaa5/lib/xmerl/src/xmerl_xsd.erl#L30-L50

Thank you, although I am wondering whether that’s feasible. I mean w/o reimplementing the thing. Is there a place where I could simply provide the fun?
al2o3cr
I suspect you may need to supply your own
fetch_funoption toxmerl_xsd- the default one only matcheshttp:URIs:https://github.com/erlang/otp/blob/master/lib/xmerl/src/xmerl_xsd.erl#L5249-L5250

So… it’s been some time since the last post here
and I have some XMLs to process both directions, with XSD support, and I have problem with external resources there. The XSD uses types definitions referenced as external URL (
https:// …) when trying to process the XSD (using:xmerl_xsd.process_schema/1) I get:enoenterror related to those external resources.Is there a way to make
xmerl[_xsd]fetch them as needed?veverkap
Thanks!

Check out GitHub - chulkilee/ex_scems: A Sentinel Cloud EMS Web Services wrapper in Elixir · GitHub.
Basically I use
SweetXml.transform_by/2and then pass map intostruct!/2.I wrote it a while ago, so I may want to do it different way now though

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

This is also the case with
Scrapeand it actually suffers some compilation issues because of having to compile rust in a rather brittle way. The only way I could make it work was to actually go into the deps manually and run a cargo command.Still good, though.

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.
