I’m not sure why you’re getting those XML-related errors… it’s possibly some issue with the PHP install (or the XML extensions to PHP, specifically) on your server.
Regardless, those are just notices. The actual status here shows that the import was completed, had only 1 row, and that was skipped. If you have logging enabled, the CSV Import plugin will log when and why it skips an item. Things like incorrect or invalid URLs for files are a common cause.
