XML Transformation with XSL error - please really need answer

I've tried transforming my XML to HTML

It already says transformation completed, but the new document generated says

Ln 6 Col 6 - The element type "link" must be terminated by the matching end-tag "". 1 Error

I've tried adding closing tag, then it just keeps showing another error...

Please download the xml,xsl file here:

Thank you very much
