In what scenarios would using XML with PHP be more beneficial than using a relational database management system, and how can developers optimize their use of XML in PHP projects?

When dealing with small to medium-sized datasets that require flexibility in data structure and easy manipulation, using XML with PHP can be more beneficial than a relational database management system. Developers can optimize their use of XML in PHP projects by utilizing SimpleXML functions for parsing and manipulating XML data efficiently. 

// Example of optimizing XML use in PHP project
$xmlString = '<?xml version="1.0"?>
<products>
  <product>
    <name>Product 1</name>
    <price>10.99</price>
  </product>
  <product>
    <name>Product 2</name>
    <price>20.99</price>
  </product>
</products>';

$xml = simplexml_load_string($xmlString);

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