## Cast boolean values
372+
> By default boolean values from the array will be cast to the string 'true' or 'false'. You can choose to cast it to any (string) value you like. This method only works on real boolean values, so strings with the value 'true' and 'false' are untouched.

> `->setCastBooleanValueTrue(string $value = 'true')`
375+
376+
> `->setCastBooleanValueFalse(string $value = 'false')`
377+
378+
```php
379+
$array = [
380+
'StringTrue' => 'true',
381+
'StringFalse' => 'false',
382+
'BooleanTrue' => true,
383+
'BooleanFalse' => false
384+
];
385+
```
386+
387+
Default:
388+
```xml
389+
<?xml version="1.0" encoding="UTF-8"?>
390+
<root>
391+
<StringTrue>true</StringTrue>
392+
<StringFalse>false</StringFalse>
393+
<BooleanTrue>true</BooleanTrue>
394+
<BooleanFalse>false</BooleanFalse>
395+
</root>
396+
```
397+
398+
Usage:
399+
```php
400+
$xml_string = $converter->setCastBooleanTrue('Yes')->setCastBooleanFalse('No')->toXmlString($array);
401+
```
402+

410+
<BooleanFalse>No</BooleanFalse>
411+
</root>
412+
```
413+
414+
415+
416+
## Cast NULL values
417+
> By default null values from the array will have no value in the XML, so the tag looks something like this: `<MyTag/>`. You can choose to cast it to any (string) value you like. This method only works on real 'null' values, so strings with the value `'null'` or empty strings `''` are untouched.
