Convert PHP output to XML - creating RSS feed

[Your1fan]

Current code gives me output to "li", and I want to adjust the output to be in valid XML so I can create RSS feed from that list. Any advice?Here is my code so far:\[code\]<?phpsession_start();mb_internal_encoding( 'UTF-8' );require_once('../config.php');require_once('../dbconnect.php');echo ' <div class="tagsz clearfix"> ';echo "<ul id='mytags_ara'>";echo "<h2 class='title'>English Trends</h2>";echo ' <div class="tagsz clearfix"> '; echo "<ul id='mytags_en'>"; $query = "SELECT hashtag, sum(count) as total FROM `trending_topics` WHERE lang=0 and hashtag != '' and date >= date_sub(left(now(), 10), interval 1 day) group by hashtag order by total desc"; $res = mysql_query($query); $index = 0; $hashtags = null; while($row = mysql_fetch_assoc($res) ) { $hashtag = $row['hashtag']; if( strtolower($hashtag) != 'newnew' && strtolower($hashtag) != 'new' && strtolower ($hashtag) != 'more' ) { echo "<li><a class='size".$index."'".$hashtag."'>#".$hashtag."</a></li>"; $index++; } if($index==6) break;} echo "</ul>"; echo "</div>"; ?>\[/code\]
