/**
|
|
* A view class that is used for creating XML responses.
|
|
*
|
|
* By setting the '_serialize' key in 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(array('posts' => $posts, '_serialize' => 'posts'));`
|
|
*
|
|
* When the view is rendered, the `$posts` view variable will be serialized
|
|
* into XML.
|
|
*
|
|
* **Note** The view variable you specify must be compatible with Xml::fromArray().
|
|
*
|
|
* You can also define `'_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->set('_serialize', array('posts', 'users'));
|
|
* }}}
|
|
*
|
|
* The above would generate a XML object that looks like:
|
|
*
|
|
* `<response><posts>...</posts><users>...</users></response>`
|
|
*
|
|
* If you don't use the `_serialize` key, you will need a view. You can use extended
|
|
* views to provide layout like functionality.

* @package Cake.View
