Try this

<?php
$sample = '<p>Sample</p><p>Sample 2</p>';

header('Content-type: text/xml');
$output = '<rss version="2.0">';
$output .= '<channel>';
$output .= '<description>'. strip_tags(utf8_encode(html_entity_decode($sample))).'</description>';
$output .= '</channel>';
$output .= '</rss>';
echo($output);

Result:

<rss version="2.0">
    <channel>
        <description>
            <p>Sample</p>
            <p>Sample 2</p>
        </description>
    </channel>
</rss>
