Hello,
I had same problem, I was trying to pull data from rss feed but i couldn’t get full text but finally i solved the problem. You can do nothing with RSS but you can change your PHP code to make it work.
If you replace <content:encoded> tag with <content> by using php code, and pull it like $desc = $xml ->channel->item[$i]->content;
It will work. This is how i solved the problem.
Thanks
Musti
