Each channel is required to contain at least three elements: 'title', 'link', and 'description'.
You can use the getLink, getTitle, and getDescription methods to obtain and present this data to the user:
require_once('somepath/xml_domit_rss.php');
$rssdoc =& new xml_domit_rss_document('http://www.somesite.com/rss.xml',
'./', 3600);
$numChannels = $rssdoc->getChannelCount();
for ($i = 0; $i < $numChannels; $i++) {
$currentChannel =& $rssdoc->getChannel($i);
//echo channel info
echo "<h2><a href=\"" . $currChannel->getLink() . "\" target=\"_child\">" .
$currChannel->getTitle() . "</a>";
echo " " . $currChannel->getDescription() . "</h2>\n\n";
//iterate through item elements
//..
}
