RSS Feed in Sidebar

[opus]

i'm trying to include an RSS feed of headlines to my sidebar. is there anyone who can tell me how to pull that off?

this is the code I want to include from my file blogfeed.php. i know that i can't just copy and paste this into the template.

PHP Code:


    
    $feed = 'http://www.trickology.com/xmlsrv/rss2.php?blog=1';

    class RSSParser { 
    
        var $insideitem = false; 
        var $tag = ""; 
        var $title = ""; 
        var $link = ""; 
    
        function startElement($parser, $tagName, $attrs) { 
             if ($this->insideitem) { 
                  $this->tag = $tagName; 
             } elseif ($tagName == "ITEM") { 
                  $this->insideitem = true; 
             } 
        } 
    
        function endElement($parser, $tagName) { 
             if ($tagName == "ITEM") { 
                  printf("<a href='%s' class='headlines'>%s</a><br>", 
                     trim($this->link),htmlspecialchars(trim($this->title))); 
                  $this->title = ""; 
                  $this->description = ""; 
                  $this->link = ""; 
                  $this->insideitem = false; 
             } 
        } 
    
        function characterData($parser, $data) { 
             if ($this->insideitem) { 
                  switch ($this->tag) { 
                        case "TITLE": 
                        $this->title .= $data; 
                        break; 
                        case "LINK": 
                        $this->link .= $data; 
                        break; 
                  } 
             } 
        } 
    } 
    
    $xml_parser = xml_parser_create(); 
    $rss_parser = new RSSParser(); 
    xml_set_object($xml_parser,&$rss_parser); 
    xml_set_element_handler($xml_parser, "startElement", "endElement"); 
    xml_set_character_data_handler($xml_parser, "characterData"); 
    $fp = fopen($feed,"r") 
        or die("Error reading RSS data."); 
    while ($data = fread($fp, 4096)) 
        xml_parse($xml_parser, $data, feof($fp)) 
             or die(sprintf("XML error: %s at line %d",  
                  xml_error_string(xml_get_error_code($xml_parser)),  
                  xml_get_current_line_number($xml_parser))); 
    fclose($fp); 
    xml_parser_free($xml_parser);
