title: transform.Unmarshal
|
|
description: "`transform.Unmarshal` (alias `unmarshal`) parses the input and converts it into a map or an array. Supported formats are JSON, TOML, YAML, XML and CSV."

signature: ["RESOURCE or STRING | transform.Unmarshal [OPTIONS]"]
|

|
|
The function accepts either a `Resource` created in [Hugo Pipes](/hugo-pipes/) or via [Page Bundles](/content-management/page-bundles/), or simply a string. The two examples below will produce the same map:
|
|
|
|
```go-html-template
|
|
{{ $greetings := "hello = \"Hello Hugo\"" | transform.Unmarshal }}`
|
|
```
|
|
|
|
```go-html-template
|
|
{{ $greetings := "hello = \"Hello Hugo\"" | resources.FromString "data/greetings.toml" | transform.Unmarshal }}
|
|
```
|
|
|
|
In both the above examples, you get a map you can work with:
|
|
|
|
```go-html-template
|
|
{{ $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:
|
|
|
|
```go-html-template
|
|
{{ $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 }}`:
|
|
|
|
```xml
|
|
<root>
|
|
<message>
|
|
<title>Hugo rocks!</title>
|
|
<description>Thanks for using Hugo</description>
|
|
</message>
|
|
</root>
|
|
```
|
|
|
|
The following example lists the items of an RSS feed:
|
|
|
|
```go-html-template
|
|
{{ 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 }}
|
|
```
