This document contains PHP code to retrieve an RSS feed from a URL, parse it to extract item titles and links, and output the results as formatted HTML. It opens the feed URL, reads it into a string, then uses regular expressions to extract specific tags from each item and output them with hyperlinks.

1. <?
$feed = 'http://rss.terra.com.br/0,,EI4795,00.xml';
ini_set('allow_url_fopen', true);
$fp = fopen($feed, 'r');
$xml = '';
while (!feof($fp)) {
$xml .= fread($fp, 128);
}
fclose($fp);
function untag($string, $tag)
{
$tmpval = array();
$preg = "|<$tag>(.*?)</$tag>|s";
preg_match_all($preg, $string, $tags);
foreach ($tags[1] as $tmpcont){
$tmpval[] = $tmpcont;
}
return $tmpval;
}
$items = untag($xml, 'item');
$html = '<p>';
foreach ($items as $item) {
$title = untag($item, 'title');
$link = untag($item, 'link');
$html .= '<font face="Tahoma" size="2" color="#006699"><a
href="' . $link[0] . '" target="_blank">' . $title[0] .
"</a></font></b><br/><br>n";
}
$html .= '</p>';
echo $html;
