How can PHP developers improve their code readability and maintainability when working with XML data and SimpleXMLElement objects?

To improve code readability and maintainability when working with XML data and SimpleXMLElement objects in PHP, developers can use proper indentation, comments, and meaningful variable names. They can also break down complex operations into smaller, more manageable functions and classes. 

// Example of improving code readability and maintainability when working with XML data and SimpleXMLElement objects

$xmlString = '<root><item><name>Item 1</name><price>10.00</price></item><item><name>Item 2</name><price>20.00</price></item></root>';

$xml = new SimpleXMLElement($xmlString);

// Loop through each item and display its name and price
foreach ($xml->item as $item) {
    $itemName = (string) $item->name;
    $itemPrice = (float) $item->price;
    
    echo "Item: $itemName, Price: $itemPrice\n";
}
