Class XmlView

A view class that is used for creating XML responses.

By setting the 'serialize' option in view builder of your controller, you can specify a view variable that should be serialized to XML and used as the response for the request. This allows you to omit views + layouts, if your just need to emit a single view variable as the XML response.

In your controller, you could do the following:

$this->set(['posts' => $posts]);
$this->viewBuilder()->setOption('serialize', true);

When the view is rendered, the $posts view variable will be serialized into XML.

Note The view variable you specify must be compatible with Xml::fromArray().

You can also set 'serialize' as an array. This will create an additional top level element named <response> containing all the named view variables:

$this->set(compact('posts', 'users', 'stuff'));
$this->viewBuilder()->setOption('serialize', true);

The above would generate a XML object that looks like:

<response><posts>...</posts><users>...</users></response>

You can also set 'serialize' to a string or array to serialize only the specified view variables.

If you don't set the serialize option, you will need a view. You can use extended views to provide layout like functionality.

    • config - Used to store the cached element in a custom cache configuration.
    • key - Used to define the key used in the Cache::write(). It will be prefixed with element_
  • callbacks - Set to true to fire beforeRender and afterRender helper callbacks for this element. Defaults to false.

  • ignoreMissing - Used to allow missing elements. Set to true to not throw exceptions.
