In what scenarios would using XML document-based storage be more advantageous than relational database storage for PHP applications like a Zuchtdatenbank?

Using XML document-based storage may be more advantageous than relational database storage for PHP applications like a Zuchtdatenbank when the data structure is hierarchical and semi-structured, when the data needs to be easily portable and self-descriptive, or when flexibility in schema changes is required. XML allows for storing data in a hierarchical format with nested elements and attributes, making it easier to represent complex relationships and data structures compared to relational databases. 

<?php
// Example of using XML document-based storage in PHP

// Create a new XML document
$xml = new DOMDocument();
$xml->formatOutput = true;

// Create a root element
$zuchtdatenbank = $xml->createElement('zuchtdatenbank');
$xml->appendChild($zuchtdatenbank);

// Add data as child elements
$animal = $xml->createElement('animal');
$animal->setAttribute('id', '1');
$animal->appendChild($xml->createElement('name', 'Fluffy'));
$animal->appendChild($xml->createElement('breed', 'Persian'));
$animal->appendChild($xml->createElement('age', '5'));
$zuchtdatenbank->appendChild($animal);

// Save the XML document to a file
$xml->save('zuchtdatenbank.xml');

echo 'XML data saved successfully.';
?>
