# XML

Extracts data from an XML file.

```php
$etl->extract('xml', 'path/to/file.xml', $options);
```

## Options

### Columns

| Type  | Default value |
| ----- | ------------- |
| array | `null`        |

To select which columns will be extracted, use the path (without the loop path) of the value. Use `@` to select attributes:

```php
$options = ['columns' => [
    'id' => '/@id',
    'name' => '/profile/name',
    'email' => '/profile/email',
]];
```

### Loop

The path to loop through.

| Type   | Default value |
| ------ | ------------- |
| string | /             |

To select which columns will be extracted, use the path (without the loop path) of the value. Use `@` to select attributes:

```php
$options = ['loop' => '/users/user'];
```
