How can PHP developers utilize SimpleXML or XML DOM to improve the readability and maintainability of XML output in their scripts?

When working with XML output in PHP scripts, developers can utilize SimpleXML or XML DOM to improve readability and maintainability. SimpleXML provides an easy-to-use object-oriented interface for accessing and manipulating XML data, while XML DOM allows for more fine-grained control over the XML structure. By using these tools, developers can simplify the process of working with XML data and make their code more organized and easier to understand. 

// Using SimpleXML to parse XML data and output it in a more readable format

$xmlString = '<root><item><name>Apple</name><price>1.99</price></item><item><name>Orange</name><price>2.49</price></item></root>';

$xml = simplexml_load_string($xmlString);

foreach ($xml->item as $item) {
    echo "Name: " . $item->name . ", Price: $" . $item->price . "<br>";
}
