extracting and assembling links from xml

[Anon]

The code below extracts <TITLE> and <LINK> elements from a standard rss-type xml file (<ITEM><TITLE><LINK><DESCRIPTION></ITEM>).

I am uncertain how this works. I see how ereg is used to parse each line for an instance of the <TITLE> tag and then passes it into $title. How is <LINK> assembled into the array? How could I pass <DESCRIPTION> into the array as well?

$startat = "</image>";
$linkstr = "link";
$exclude = "";
$startnum = 0;

// determine which line to begin grabbing the links
for ($i=0;$i<count($lines);$i++) {
if (ereg($startat,$lines[$i],$regs)) {
$startnum = $i;
break;
}
}

// extract the links and assemble into array $links
$links = array();
for ($i=$startnum;$i<count($lines);$i++) {
if (count($links)>=$this->listings) break;
if (ereg("<title>(.*)</title>",$lines[$i],$regs)) {
if ($regs[1] == $exclude) {$i+=1; break;}
$title = $regs[1];
$title = ereg_replace("&amp;apos;","'",$title);
}

  else if (ereg("<$linkstr>(.*)</$linkstr>",$lines[$i],$regs)) {
    $links[$title] = $regs[1];
  }

}

return $links;

Note- the LINK tag was stripped out of the post.

Manually parsing through XML files isn't the best solution. Instead, let PHP do the work by using its XML parser:

Your right. I would if I could, but my provider (Verio) does not support the expat functions.
