function fargo2opml ($opmlfile) {

'url' => '',
), $opmlfile);
function parse_opml($xml,$depth=1) {
if (count($xml->children()) > 0) {
echo'<ul>';
}
foreach ($xml->children() as $child) {
if ($child['url']) {
echo '<li><a href='.$child['url'].'>'.$child['text'].'</a></li>';
}
else {
echo '<li>'.$child['text'].'</li>'; // level 1 outlines
}
parse_opml($child,$depth+1); // nested outlines
}
if (count($xml->children()) > 0) {
echo '</ul>';
}
