Well, the root problem is as stated in the error message. If you want to avoid that ugly result being displayed to the user, you'll need to use a try/catch block to catch the exception and handle it in whatever way you'd like, e.g.:

<?php
// . . .
$data = curl_exec($ch);
curl_close($ch);
try
{
   $doc = new SimpleXmlElement($data, LIBXML_NOCDATA);
   // . . .
}
catch Exception($e)
{
   echo "<pre>DEBUG:\n$e\n\nReceived text:\n\n$data</pre>";
}

After debugging the current issue, you may want to change the actual processing in the catch block to something more user-friendly for the live version.

PS: Please make use of this forum's [php]...[php] tags for PHP code sample, and [code]...[/code] tags for non-PHP code.

sir thanks for ur help but still it is not running

can u send me the whole code for it.

[NogDog]

I just realized I had a misplace parenthesis. The "catch" line should have been:

catch(Exception $e) 

[NogDog]

I ran this, and did not trigger the exception:

<?php
// show all run-time errors
ini_set('display_errors', 1); // change to 0 for live version
error_reporting(E_ALL);

$ch = curl_init("http://www.hindustantimes.com/RSSFeed/RssFeed.ashx?c=Chunk-HT-UI-HomePage-TopStories/");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HEADER, 0);
set_time_limit(120);
$data = curl_exec($ch);
curl_close($ch);
// use try/catch to handle exceptions
try
{
   $doc = new SimpleXmlElement($data, LIBXML_NOCDATA);
   print_r($doc);
   if(isset($doc->channel))
   {
      parseRSS($doc);
   }
   if(isset($doc->entry))
   {
      parseAtom($doc);
   }
}
catch(Exception $e)
{
   echo "<pre>DEBUG:\n".$e->get_message()."\n\nReceived text:\n\n".
        htmlspecialchars($data)."</pre>";
}
function parseRSS($xml)
{
   echo "<strong>".$xml->channel->title."</strong>";
   $cnt = count($xml->channel->item);
   for($i=0; $i<$cnt; $i++)
   {
      $url     = $xml->channel->item[$i]->link;
      $title     = $xml->channel->item[$i]->title;
      $desc = $xml->channel->item[$i]->description;

      //echo '<a href="'.$url.'">'.$title.'</a>'.$desc.'';
      echo "<img src='bullet.gif' hspace='0' vspace='0' border='0'>&nbsp;";
      echo '<font size=2><a href="'.$url.'" target="_blank()">'.$title.'</a></font><br />';
   }
}
?>

now the error is -

Fatal error: Call to undefined method Exception::get_message() in C:\wamp\www\asheesh\test.php on line 36

[NogDog]

Sorry, that should be $e->getMessage() (not $e->get_message()).
