Transform an array into a SimpleXMLElement

### Options

- `format` If create childs ('tags') or attributes ('attributes').
- `pretty` Returns formatted Xml when set to `true`. Defaults to `false`
- `version` Version of XML document. Default is 1.0.
- `encoding` Encoding of XML document. If null remove from XML header. Default is the some of application.
- `return` If return object of SimpleXMLElement ('simplexml') or DOMDocument ('domdocument'). Default is SimpleXMLElement.

Using the following data:

```
$value = [
'root' => [
'tag' => [
'id' => 1,
'value' => 'defect',
'@' => 'description'
]
]
];
```

Calling `Xml::fromArray($value, 'tags');` Will generate:

`<root><tag><id>1</id><value>defect</value>description</tag></root>`

And calling `Xml::fromArray($value, 'attributes');` Will generate:

`<root><tag id="1" value="defect">description</tag></root>`

@param array|\Cake\Collection\Collection $input Array with data or a collection instance.
@param string|array $options The options to use or a string to use as format.
@return \SimpleXMLElement|\DOMDocument SimpleXMLElement or DOMDocument
@throws \Cake\Utility\Exception\XmlException
