Mysterious error with XML in Google Merchants

Question

I've written an exporter in php extrancting data from mysql db. Tags are appropriate, the structure is I hope valid, but smeg 1 knows why (I couldn't find a fault) it doens't want to consume a link from XML pointing to my product in shop. It says: Error of formating XML. The system couldn't process the source 2. I'm adding a picture.

Does anyone have an experience with this type of problem? Thank you for you advices!
