php Fatal error: Call to a member function children() on a non-object

Trying to make this peace of code work. But I get the Fatal error. I am not sure how to fix this. Any help would be appreciate it. The error is for this line: $counts = $sxml-> children('http://a9.com/-/spec/opensearchrss/1.0/');

// generate feed URL
      $feedURL = "http://gdata.youtube.com/feeds/api/videos/-/{$q}
      ?orderby=viewCount&max-results={$i}";

      // read feed into SimpleXML object
      $sxml = simplexml_load_file($feedURL);

      // get summary counts from opensearch: namespace
      $counts = $sxml-> children('http://a9.com/-/spec/opensearchrss/1.0/');
      //$counts = $sxml-> children('http://www.opensearch.org/Specifications/OpenSearch/1.1');

      $total = $counts->totalResults;
      $startOffset = $counts->startIndex; 
      $endOffset = ($startOffset-1) + $counts->itemsPerPage;

To avoid getting this error, you should use condition like:

if(false !== $sxml){
      //your code
}

simplexml_load_file has failed. It returns false (a none object) on failure.

Either your server can't access the URL, or it is returning invalid XML.

From the Manual:

Returns an object of class SimpleXMLElement with properties containing the data held within the XML document, or FALSE on failure.
