I am having problems using this. I am trying to get yahoo news feeds. I get the following error.

A PHP Error was encountered

Severity: Warning

Message: SimpleXMLElement::__construct(): Entity: line 23: parser error : Input is not proper UTF-8, indicate encoding ! Bytes: 0xA0 0x6D 0x65 0x6E

Filename: libraries/rssparser.php

Line Number: 90 

the link i am trying to parse is UTF-8 ...

http://news.search.yahoo.com/news/rss?p=home+intrusion&ei=UTF-8&fl=0&x=wrt

 

what is weird is that this one works fine.

http://news.search.yahoo.com/news/rss?p=business+theft&ei=UTF-8&fl=0&x=wrt

I’m using RSSParser to pull in my own Wordpress(.org) blog feed into another site of mine.  I’ve modified the library a bit in order to pull in the full post content along with the excerpt (by default, RSSParser will only pull in the excerpt, by taking $item->description):

This block of code:

//Build the item array
      foreach ($xml->channel->item as $item)
      {
           $data = array();
           $data['title'] = $item->title;
           $data['description'] = $item->description;
           $data['pubDate'] = $item->pubDate;
           $data['link'] = $item->link;
           $this->data[] = $data;
      } 

Was modified to this block of code:

//Build the item array
      foreach ($xml->channel->item as $item)
      {
           $data = array();
           $data['title'] = $item->title;
           $data['description'] = $item->description;
           $content = $item->children('http://purl.org/rss/1.0/modules/content/');
           $data['content'] = (string)trim($content->encoded);
           $data['pubDate'] = $item->pubDate;
           $data['link'] = $item->link;
           $this->data[] = $data;
      } 

I learned about how to do this from the post Using SimpleXML To Parse RSS Feeds, so if you’d like to learn more about the two lines I added you should check out that post.

I’m having an issue in my environment (Ci2/MAMP) where I get an error when I am trying to load the RSSParser.

I use the below code:

//Load the shiny new rssparse
  $this->load->library('RSSParser', array('url' => 'http://link.to/rss.xml', 'life' => 2));
  //Get six items from the feed
  $data = $this->rssparser->getFeed(6);

  foreach ($data as $item) :
    // do stuff with $item['title'], $item['description'], etc.
  endforeach; 

And I get this error:

Severity: Notice

Message: Undefined property: CI_Loader::$rssparser

Filename: theme/content.php

Line Number: 28 

Has anyone come across this/know how to fix it?

nnash - I hope this is helpful (I’m not totally certain it will be)...

I have the load code ($this->load->library) in my controller.  The error you provide displays your code is in “theme/content.php”.  I’m not sure if that matters.

I get items from the feed differently. I’m also not certain this matters. You use:
$data = $this->rssparser->getFeed(6);

I use:
$data = array(‘posts’ => $this->rssparser->getFeed(6));


I hope this is useful, but like I said - I’m not sure it will be.  I’m just spotting differences…

I’m sorry to hear that, nnash…
The only other thing that I can think of is maybe the RSSParser.php file isn’t in the application\libraries folder.

I had it in system\libraries, but after I moved it to application\libraries I still got the same error.

Edit: I was able to fix my issues by placing the RSSParser snippet in the index(); of my controller.

Hey Summer Student.

I had the same error as you.  Can you share the fix?

Thanks.

If you don’t require caching or if caching is giving you a headache you can try using the modified library below which is basically the same as the original but with all caching references removed.

Also changed the item array to return strings and not xml objects.

I’ve slightly improved and ‘tidied’ up the library - https://github.com/ollierattue/codeigniter-rssparser

I have added some functions:

- clear function for recursive parser calls
- feed author (creator) field added to the parsed data

function parse()
 {
  // Are we caching?
  if ($this->cache_life != 0)
  {
   $this->CI =& get_instance();
      $cache_dir = $this->CI->config->item('cache_path');
   $filename = $cache_dir.'rss_Parse_'.md5($this->feed_uri);

   // Is there a cache file ?
   if (file_exists($filename))
   {
    // Has it expired?
    $timedif = (time() - filemtime($filename));

    if ($timedif < ( $this->cache_life * 60))
    {
     $rawFeed = file_get_contents($filename);
    }
    else
    {
     // So raise the falg
     $this->write_cache_flag = true;
    }
   }
   else
   {
    // Raise the flag to write the cache
    $this->write_cache_flag = true;
   }
  }

  // Reset
  $this->current_feed['title'] = '';
  $this->current_feed['description'] = '';
  $this->current_feed['link'] = '';
  $this->data = array();
  $this->channel_data = array();

  // Parse the document
  if (!isset($rawFeed))
  {
   $rawFeed = file_get_contents($this->feed_uri);
  }

  $xml = new SimpleXmlElement($rawFeed);

  if ($xml->channel)
  {
   // Assign the channel data
   $this->channel_data['title'] = $xml->channel->title;
   $this->channel_data['description'] = $xml->channel->description;

   // Build the item array
   foreach ($xml->channel->item as $item)
   {
    $data = array();
    $data['title'] = (string)$item->title;
    $data['description'] = (string)$item->description;
    $data['pubDate'] = (string)$item->pubDate;
    $data['link'] = (string)$item->link;

    $this->data[] = $data;
   }
  }
  else
  {
   // Assign the channel data
   $this->channel_data['title'] = $xml->title;
   $this->channel_data['description'] = $xml->subtitle;

   // Build the item array
   foreach ($xml->entry as $item)
   {
    $data = array();
    $data['id'] = (string)$item->id;
    $data['title'] = (string)$item->title;
    $data['description'] = (string)$item->content;

     $data = call_user_func($this->callback, $data, $item);
    }
     
    $this->data[] = $data;
   }
  }

  // Do we need to write the cache file?
  if ($this->write_cache_flag)
  {
   if (!$fp = @fopen($filename, 'wb'))
   {
    echo "RSSParser error";
    log_message('error', "Unable to write cache file: ".$filename);
    return;
   }

   flock($fp, LOCK_EX);
   fwrite($fp, $rawFeed);
   flock($fp, LOCK_UN);
   fclose($fp);
  }

  return TRUE;
 }

/* Initialize the feed data */ 
 function clear()

  $this->channel_data = array();
