Hugo: Add XML as a support data format

[bzerangue]

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 why XML is NOT amongst the available formats?

It would be great to add XML as an available data type for the /data folder.

@bzerangue This would be fantastic. Not sure if something like https://github.com/beevik/etree would help said efforts...

+1 on this. Type "XML" could then act as a flag to invoke DOCTYPE parsing and optional validation.

Having a getXML similar to getJSON would be useful in creating "planets" from feeds. Ref: https://discourse.gohugo.io/t/anyone-here-interested-in-a-hugo-planet/15092.

It would be great to add XML as an available data type for the /data folder.

Not just the data/ folder, my proposal is to allow remote XML fetching. Once RSS/ATOM feeds can be fetched, we can maintain theme components that do the parsing of the fetched XML feeds.

This looks promising: https://github.com/clbanning/mxj

But note that mapping arbitrary XML into a map isn't trivial.

This'll be great for surfacing RSS from other sources like Medium

[raybellis]

+1 from me, too - I'd like to be able to include references from the RFC index, but it's only published in XML format.

I'm working on a Go library to parse mixed content. If anyone can propose an API (i.e. interfaces) that would be useful for Hugo, I could give it a whack.

[stephlocke]

On the RSS specific side, I currently leverage a site that parses RSS to JSON for consumption

{{ $rssJ := getJSON "https://api.rss2json.com/v1/api.json?rss_url=https%3A%2F%2Fmedium.com%2Ffeed%2Fnightingale-hq" }}


{{ range $rssJ.items }}
    {{ $post := . }}
    <div class="col-12 col-md-6 col-lg-4 mb-2 mr-2 pb-8 blog" style="background-image: url({{ $post.thumbnail }});">
    <a href="{{ $post.link }}" target="_blank" alt="{{ $post.title }}">
    <h2>{{ $post.title }}</h2>
    </a>
    <h3>{{ $post.author }}</h3>
    </div>
{{ end }}

If this request is too complex as is, what about simplifying it to a getRSS function? I know for me the need for getXML is simply so that I can have Hugo read in RSS feeds.

Agreed, this would be fantastic. From the library tech perspective -- we are experimenting with using Hugo to generate Special Collections Finding Aids from Encoded Archival Description (EAD) -- an XML format widely used by libraries.
