PHP and XML: Parsing RSS 1.0

A great article - exactly what I needed. In addition, could anyone tell me how to limit the number of items that are displayed. For example, if I wanted to list just the latest three items from a feed that has 25 items listed, how would I tell the parser to stop at 3?

Thanks

Great Article! One of the best on this subject.

Very timely! I have been looking for a replacement for the excellent MagpieRSS, and the only real option at this stage seems to be writing our own RSS reader.

This article worked perfectly for me with fopen enabled. But my webhost has fopen disabled. I had to plug in the following code to get it to work without using fopen:

 $ch = curl_init();
  curl_setopt( $ch, CURLOPT_URL, "http://www.example.com/headlines.jsp" );
  curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
  $data = curl_exec( $ch );
  if( empty( $data )) die("Error reading RSS data.");
  
  xml_parse($xml_parser, $data ) or 
      die(sprintf("XML error: %s at line %d",
          xml_error_string(xml_get_error_code($xml_parser)), 
          xml_get_current_line_number($xml_parser)));
  
  curl_close($ch);

  curl_close($ch); 

can you assign a timeout using the curl() method?

thanks

Never mind. I had the rdf extention marked wrong. Works like a charm.

if the file is remote, you can grab the xml content with cURL or fsocketopen
