What are the differences between loading XML data using DOMDocument and simplexml_load_file in PHP, and how can issues like base64 encoding be addressed in each case?

When loading XML data using DOMDocument in PHP, you can access base64 encoded data by using the `base64_decode` function. On the other hand, when using `simplexml_load_file`, you can directly access the base64 encoded data as a string. To address base64 encoding when loading XML data using DOMDocument: 

$dom = new DOMDocument();
$dom->load('example.xml');
$base64EncodedData = $dom->getElementsByTagName('base64EncodedData')->item(0)->nodeValue;
$decodedData = base64_decode($base64EncodedData);
```

To address base64 encoding when loading XML data using simplexml_load_file:
```php
$xml = simplexml_load_file('example.xml');
$base64EncodedData = (string)$xml->base64EncodedData;
$decodedData = base64_decode($base64EncodedData);
