RSS Feed in Sidebar
 
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);

Hmm.. A first step would be to marry that code with this hack I wrote

https://vborg.vbsupport.ru/showthread.php?t=70848

That way you'd have a cron job that would output the information periodically into a template. You could then use the PHPINCLUDE_START template to parse that template and then include the template in your header (or wherever) to get it to post.
