  <p>My ObjC code</p>
  
  <pre><code>CXMLDocument *rssParser = [[[CXMLDocument alloc] initWithContentsOfURL:url options:0 error:nil] autorelease];
  
      // Create a new Array object to be used with the looping of the results from the rssParser
      NSArray *resultNodes = NULL;
  
      // Set the resultNodes Array to contain an object for every instance of an  node in our RSS feed
      resultNodes = [rssParser nodesForXPath:@"Link" error:nil];
  </code></pre>
