transform.Unmarshal

Syntax

RESOURCE or STRING | transform.Unmarshal [OPTIONS]

The function accepts either a Resource created in Hugo Pipes or via Page Bundles, or simply a string. The two examples below will produce the same map:

{{ $greetings := "hello = \"Hello Hugo\"" | transform.Unmarshal }}`

{{ $greetings := "hello = \"Hello Hugo\"" | resources.FromString "data/greetings.toml" | transform.Unmarshal }}

In both the above examples, you get a map you can work with:

{{ $greetings.hello }}

The above prints Hello Hugo.

CSV Options

Unmarshal with CSV as input has some options you can set:

delimiter

The delimiter used, default is ,.

comment

The comment character used in the CSV. If set, lines beginning with the comment character without preceding whitespace are ignored.:

Example:

{{ $csv := "a;b;c" | transform.Unmarshal (dict "delimiter" ";") }}

XML data

As a convenience, Hugo allows you to access XML data in the same way that you access JSON, TOML, and YAML: you do not need to specify the root node when accessing the data.

To get the contents of <title> in the document below, you use {{ .message.title }}:

<root>
    <message>
        <title>Hugo rocks!</title>
        <description>Thanks for using Hugo</description>
    </message>
</root>

The following example lists the items of an RSS feed:

{{ with resources.Get "https://example.com/rss.xml" | transform.Unmarshal }}
    {{ range .channel.item }}
        <strong>{{ .title | plainify | htmlUnescape }}</strong><br />
        <p>{{ .description | plainify | htmlUnescape }}</p>
        {{ $link := .link | plainify | htmlUnescape }}
        <a href="{{ $link }}">{{ $link }}</a><br />
        <hr>
    {{ end }}
{{ end }}
