How can a PHP developer with limited experience in scripting modify existing code, like the one in the forum thread, to accommodate reading XML data instead of HTML data?

To modify existing PHP code to read XML data instead of HTML data, the developer can use PHP's built-in SimpleXML functions to parse and extract information from the XML file. By replacing the HTML parsing logic with XML parsing logic, the developer can access the XML data and manipulate it as needed. Below is an example code snippet demonstrating how to read XML data in PHP:

// Load the XML file
$xml = simplexml_load_file('data.xml');

// Access specific elements in the XML file
foreach ($xml->children() as $child) {
    // Process each XML element as needed
    echo $child->getName() . ": " . $child . "<br>";
}
