JavaScript: RSS auslesen

[alcaeus]

Moin Chris,

hier mal die Klasse fuer RDF-Feeds, wie ich sie verwende. Das Parsen erfolgt ueber Regular Expressions, welche ja auch in JS funktionieren. Eventuell kannst du ja die eine oder andere Idee verwenden, aber fertige Loesung kenne ich im Moment keine

Code:

<?php

class rdf_parser
{
   var $file;
   var $content = '';

   var $channel = array();
   var $items = array();

   function rdf_parser($file)
   {
      $this->file = $file;
   }

   function match($text, $elements)
   {
      $ret = array();
      foreach($elements as $element)
      {
         if(preg_match("#<$element>(.*?)</$element>#si", $text, $matches))
         {
            $ret[$element] = $matches[1];
         }
      }
      return $ret;
   }

   function parse()
   {
      $file = $this->file;
      $this->content = @implode('', @file($file));

      if(preg_match('#<channel>(.*?)</channel>#si', $this->content, $matches))
      {
         $this->channel = $this->match($matches[1], array('title', 'description', 'link'));
      }
      preg_match_all('#<item>(.*?)</item>#si', $this->content, $matches, PREG_PATTERN_ORDER);
      foreach($matches[1] as $item)
      {
         $this->items[] = $this->match($item, array('title', 'description', 'link'));
      }
   }
}

?>
