It would be nice to provide XML as an available data type to load. Currently, Hugo accepts, TOML, YAML, JSON, and CSV. Is there any reason XML is amongst the available formats?
So, in /data there iare toml/yaml/json – which all fits into the tree like data structure of /data. Adding XML to those would probably seem natuall, but you are the first asking for it. You should create a GitHub issue.
Just added the Github issue.
This would be an awesome addition.
