How can PHP developers effectively navigate and understand the documentation on handling XML attributes in PHP?

To effectively navigate and understand the documentation on handling XML attributes in PHP, developers should first familiarize themselves with the XML functions provided by PHP, such as simplexml_load_string() and simplexml_load_file(). They should then carefully read the PHP documentation on handling XML attributes, paying close attention to examples and explanations provided. Additionally, developers can experiment with sample XML files containing attributes to better understand how to access and manipulate them in their PHP code.

$xmlString = '<book genre="fiction"><title>The Great Gatsby</title></book>';
$xml = simplexml_load_string($xmlString);

// Accessing and printing the value of the 'genre' attribute
echo $xml['genre'];
