Just move all of your DOMDocument code block inside the loop after the switch.
<?php
$q=$_GET["q"];
$q2 = explode(" ",$q);
$count = count($q2);
for($i=0;$i<$count;$i++) {
//find out which feed was selected
switch ($q2[$i]) {
case "Weather":
$xml=("http://rss.weather.com/rss/national/rss_nwf_rss.xml?cm_ven=NWF&cm_cat=rss&par=NWF_rss");
break;
case "NFL":
$xml = ("http://www.nfl.com/rss/rsslanding?searchString=home");
break;
default:
exit;
break;
}
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<=4; $i++)
{
$item_title=$x->item($i)->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$item_link=$x->item($i)->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$item_desc=$x->item($i)->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;
echo ("<p><a href='" . $item_link . "'>" .
$item_title . "</a>");
echo ("<br />");
echo ($item_desc . "</p>");
}
}
?>
