Imam problem sa RSS parserom koji sam skinuo sa phpclasses-a.Naime ovaj parser je u pocetku lepo radio, ali od skoro nece nista da mi ucita samo se muci da downloaduje stranicu, ali na kraju uvek ispise no response, try again.
Incae iskoristio sam ovaj parser da parsira RSS feed sa sajta i da ga prosledjuje na wap stranicu.Ako moze neko neka pregleda kod i neka mi kaze jel ima gresaka, i koje su jer ja stvarno ne mogu da provalim.

Code:

<?php
header('Content-type: text/vnd.wap.wml');
 echo '<?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
 <wml>
 <head>
 </head>

// define hooks to rss_parser class as xml functions do not allow object methods as handlers.
function rss_start_element($parser, $name, $attributes) {
 global $rss;
 $rss->start_element($parser, $name, $attributes);
}

function rss_end_element($parser, $name) {
 global $rss;
 $rss->end_element($parser, $name);
}

function rss_character_data($parser, $data) {
 global $rss;
 $rss->character_data($parser, $data);
}

class rss_parser {

// constructor. setup parser options and handlers.
function rss_parser() {
 $this->error = '';
 $this->file = '';

 $this->channel = array();
 $this->data = '';
 $this->stack = array();
 $this->num_items = 0;

 $this->xml_parser = xml_parser_create();
 xml_set_element_handler($this->xml_parser, "rss_start_element", "rss_end_element");
 xml_set_character_data_handler($this->xml_parser, "rss_character_data");
}

function character_data($parser, $data) {
 if (empty($this->data)) $this->data = trim($data); // concatenate non-parsed data...
 else $this->data .= ' '.trim($data); // and get rid of white space.
}

function start_element($parser, $name, $attrs) {
 switch($name) {
 case 'RSS':
 break;

 $this->item[$this->num_items] = array();
 $this->num_items++;
 break;

 case 'TEXTINPUT':
 array_push($this->stack, $name);
 break;

 }
}

 eval("\$this->channel['$element']=\$this->data;"); // this does all the hard work.
 array_pop($this->stack);
 $this->data = '';
 break;
 }
}

function parse() {
 if (!($fp = @fopen($this->file, "r"))) {
 $this->error = "Could not open RSS source \"$this->file\".";
 return false;
 }
 while ($data = fread($fp, 4096)) {

 $this->error = sprintf("XML error: %s at line %d.",
 xml_error_string(xml_get_error_code($this->xml_parser)),
 xml_get_current_line_number($this->xml_parser));
 return false;
 }
 }
 xml_parser_free($this->xml_parser);
 return true;
}
} // class rss_parser.

$rss = new rss_parser();
$rss->file = 'http://news.sofub.org.yu/rss.php';
$rss->parse() or die($rss->error);
if ($rss->error) print $rss->error;

$data = $rss->channel;
$number = count($data['ITEM']);
for ($i=0; $i<3; $i++) {
echo ''.$data['ITEM'][$i]['TITLE'].' ';
echo '<a hfer="'.$data['ITEM'][$i]['LINK'].'">link</a> ';
$descript = $data['ITEM'][$i]['DESCRIPTION'];
$descript = str_replace('','',$descript);
$descript = str_replace('','',$descript);
echo $descript.' ';
echo '------- ';
}
echo '

?>
