Cannot read XML online - only locally

Hi!
There is an RSS channel: http://www.free-lance.ru/rss/all.xml
I can parse and read everything inside <channel> node except <item> node. For example, I can read information from <lastBuildDate> but cannot read the <link> which is inside <item>. SWF acts like <item> node doesn’t exist at all:

On the other hand, if I save the XML-file of the channel to local machine — everything works fine and I can read <item> nodes without problems:

What could be the reason of this behaviour?
Thanks in advance!
