What are the potential advantages and disadvantages of using SimpleXML versus DOMDocument for parsing XML in PHP?

When parsing XML in PHP, SimpleXML is generally easier to use and requires less code compared to DOMDocument. SimpleXML provides a more intuitive object-oriented approach, making it simpler to navigate and extract data from XML documents. However, SimpleXML may not be suitable for more complex XML structures or operations that require fine-grained control, in which case DOMDocument would be a better choice. 

// Using SimpleXML to parse XML
$xml = simplexml_load_string($xmlString);
foreach ($xml->children() as $child) {
    echo $child->getName() . ": " . $child . "<br>";
}
```

```php
// Using DOMDocument to parse XML
$dom = new DOMDocument();
$dom->loadXML($xmlString);
$xpath = new DOMXPath($dom);
$elements = $xpath->query('//element');
foreach ($elements as $element) {
    echo $element->nodeValue . "<br>";
}
