## 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 }}
```
