How does the use of output buffering in PHP impact the parsing of XHTML documents delivered as XML?

Output buffering in PHP can impact the parsing of XHTML documents delivered as XML because it can interfere with the correct encoding of the document. To solve this issue, you can disable output buffering before sending the XML content to the browser. 

<?php
// Disable output buffering
while (ob_get_level()) {
    ob_end_clean();
}

// Set the appropriate headers for XML content
header('Content-Type: application/xml');

// Output the XML content
echo '<?xml version="1.0" encoding="UTF-8"?>';
echo '<root>';
echo '<element>Value</element>';
echo '</root>';
?>
