Feed products from xml url doesn't work

I just installed datafeed for joomla 2.5. I can't see the possibility to feed products from xml url. There is the possibility for csv, but not for xml. I know that in 1.5 joomla version it was there. This is a change in this new 2.5 version or I am doing something wrong. If I try to feed from xml url than it says me "Unable to fetch feed". What am I doing wrong with the xml url?
Thank you for your help

Can you make a print screen? I am using 2.5 with the latest datafeed but i have the possibility for xml.

3.0 does support the same parsers as the 1.5 and 2.5 versions.

the parser should work for the native zanox feeds and the M4N type ( use the m4n parers )

If everything fails CSV should 'always' work

Currenlty zanox is quite a mess. I have seen posts on other forums reporting trouble with the marketplace feeds.
